I dont know how any controller can be expected to maintain altitude separation whilst viewing a radar screen reporting incorrect altitude information. Craziness.

[@duartesimoes508]

I believe my Company would have turned off the Radar and rely only in altitude reports, if only to escape from any accusations if something went really bad. And that's the doctrine anyway; if a display or instrument is displaying false information, either turn it off or if unable cover the display before anyone gets killed. As an instructor once told me, "the real problem is not when it stops displaying altogether but rather when it starts displaying what looks to be wrong information, or you have an _instrument disagree_ situation.

[@Jabarri74]

It wasn't even hm that gave them authorisation, the mid level ones did that. How was any of this his fault?

[@gnarthdarkanen7464]

Simply enough, you CAN'T expect any controller to manage altitude separation when dealing with false information from the equipment at hand... Even if he tries to ignore it, he's got to get that information from someone or somewhere... AND don't forget working regular 12 hour shifts, so on sleep dep' to boot. For my money, based on the information he DID have available, he acted on the CORRECT call to make, and to the best of his ability and education. In the heat of that moment, there simply wasn't a better resolution with any guarantee of the outcome... AND that still makes him an easy target for scapegoating. ;o)

[@gorillaau]

​@@gnarthdarkanen7464 Yes, one may think that you could ignore something but we keep going back to your training and everything learn that has gone before the incidenr. If a computer is saying 33,500 feet, then I will trust it. Same as a car fuel gauge saying that there is a quarter of a tank of fuel left. We learn to trust the instruments given to us.

[@gaiaiulia]

And being on duty for three consecutive twelve hour shifts! Pure criminality by the people who made the cut backs in funding and personnel for ATC and couldn't maintain the radar accuracy. How could the controller be blamed for that?

[@OfftheWallTales]

@@gaiaiulia I’m 99% sure he meant 3 days of 12 hour shifts, not 36 hours. That’s the legal terminology for it and there was no mention of him falling asleep during his shift. For a job that doesn’t require a ton of brain power, that’s normally fine. For a job that is requiring you to continuously do math, write down all calculations, speak with everyone and make sure not to forget anything? Yeah, it’s too much. What I mean is that, from my own experiences doing these exact shifts, it’s fine if it’s a repetitive task or in my case simply sitting there watching over residents of a halfway house. You still remember everything. When I was an accountant on a film? By day three I was messing up numbers constantly and had to move to set to recharge. Then all was fine.

[@gaiaiulia]

@@OfftheWallTales oh, okay, thanks. They did say consecutively. But probably like nurses, three twelve hour shifts for three consecutive days. I read it as three twelve hour shifts back to back, which hasn't been unheard of for junior hospital doctors. And yes, even twelve hour shifts three days in a row with dodgy radar is shocking. He was definitely scapegoated.

As a multiple language speaker, i sometimes find myself switching languages mid-sentence even in calm situations.

Yes, also I'm sure it was quicker to communicate and be understood in their native tongue, rather than taking that extra time to formulate it in another language and then for the other party to decipher it from the foreign language. Perhaps he would have been criticised for acting too slowly. This was a situation where the poor man couldn't win and it's only in retrospect that we can criticise his actions

[@musicbruv]

LJU and ZAG is only 135 kms as the crow flies ... the poor ATC guy had to clear the airspace in a very short time .... in those days there were no computers, the ATC used strips ... so, in utter panic, a tragic error occurred, since the Adria Airways plane had to change the altitude and in the process it crossed paths with BA ... so mid-air collision was inevitable ... the British pilot was cut in half by the wing of the in-bound DC-9 this I heard from a guy who had actually worked at the ZAG ATC

[@doctoremil2678]

I'm from Croatia. Not too long ago, our national TV station made a documentary on this accident in which they interviewed some of the eyewitnesses who had seen the immediate aftermath. It was shocking. Probably the worst was the story of a family that found a dead body of a passenger on the roof of their garden shed, and the authorities did not send anyone to take it away for several days! Obviously, most if not all of the interviewed people were very much traumatized by what they saw. But there was another thing that pissed me off: someone posted the documentary on KZbin (not sure if it's been removed), and there were so many toxic comments in which people mocked and insulted the witnesses for some slightly strange behaviours they displayed while remembering the crash. Clearly, some people have never heard of PTSD and coping mechanisms.

[@AmyAnnLand]

That's awful about those comments. I find that some people online are so quick to judge those who are in shock or suffer from PTSD. Like, they have no idea what it's like, and everyone responds differently in times of trauma. I wish they could be more empathetic.

Very few accidents touch me as much as this one did. Thank you very much for your great research and explanation. It would appear that we made major strides in direction of technological advancements in the air (TCAS, CRM) on the ground however the issues seem to stay the same. This accident, at least to me, shares some significant contributing factors as the Überlingen desaster (e.g. understaffed and overworked ATC). Fortunately this Controller did not share in the fate as the one in Überlingen did, and I would personally agree that the controller was "used" as easy scapegoat. That you for another excellent video and I am looking forward to your future videos.

[@rilmar2137]

I really appreciate the historical context! Great vid as always. Mid-air collisions like this one always break my brain - such vast skies, one might think it's impossible for two airliners to find themselves in the same place at the same time. And yet.

[@duartesimoes508]

Although the sky appears unlimited, I'd say as former Controller that more than 95% of it is permanently empty while the rest is crammed with aircraft flying in both senses in Airways with just one thousand feet vertical separation and a few nautical miles longitudinal separation. It is the only way of controlling aircraft effectively and in a predictive and economical way. But risks are always there and speeds involved are enormous. There's no much room for errors nor time to correct them. And Air traffic worldwide is increasing endlessly. The more aircraft show up, the more Sectors must be created, each one manned by a Controller, because there is of course an human limit to the number of aircraft one Controller can handle at the same time. That is why pilots are constantly changing frequency and being received by a new Controller. If there were six aircraft flying in the whole United Kingdom, for example, one Controller and one Sector would be enough... 😀

[@dougschwieder3627]

Until you find out that they route them directly to the same GPS coordinates separating them only by altitudes with as little as only 1,000 vertical feet separating them, if everybody does their job right.

[@WMAcadet]

I remember when this happened, almost 50 years ago when I was a Flight Instructor fresh out of college. This is almost the only information I have seen available about it and I thank you for making the video. I know that Gradimir Tasic is devastated to this day by it, even though I firmly believe he was not to blame and was made a patsy by the Yugoslav Government, a convenient way to let themselves off the hook. The poor guy was inconsolable afterward and I'm sure he was shaking. As an airline pilot, my bacon was saved by TCAS one day over Japan when an ANA 737 was mistakenly cleared to climb through my altitude and I missed him by about 3-400 feet as I was making the climbing right turn (a chandelle) commanded by my TCAS. I filed a report upon landing in Taipei and the company filed a report with Tokyo ATC, who claimed we did not come within 2 miles of one another, but did not submit any radar tape to prove it. The pilot of the other plane never took any evasive action, and had I not done so, we would have collided. TCAS is not useful when pilots do not do what it tells them to do IMMEDIATELY! When I told ATC what we had done and why, his only response was "Roger." Thank God I'm retired...

[@fromtheflightdeck252]

Are you with Western Michigan?

[@WMAcadet]

@@fromtheflightdeck252 No, I was flying a 747 with a brown and white paint job on it. It was the F/O's leg and ATC calmly told us to turn right heading 345, and since we were on a course of about 220 and going to TPE, I sensed something was very wrong. I told the F/O immediately to disconnect the autopilot and make the turn by hand and as he started to bank right the TCAS announced TRAFFIC...TRAFFIC...TRAFFIC...CLIMB...CLIMB...CLIMB... and we did exactly that. We had been at F280 and when we stopped the maneuver and I called Tokyo we were at F315 and heading of 345. After he said "Roger" he waited about 15 seconds and then said to descend to F280 and resume course direct to Kobe and FPR. If you are a cargo aircraft they will give passenger aircraft your altitude, make you turn off the airway so they can climb on the airway and go past you and then also make you descend. They also do not observe first come first served as we do in the US. Any Japanese aircraft will get whatever they want whenever they want at your expense. I was on the way to Hong Kong from Anchorage at F330 and was put in holding over Toyota, Japan one time for 30 minutes to allow a bunch of Japanese airliners to climb out of their departure points and pass me, then ordered to descend to a lower altitude and proceed on course when I was still almost 2,000 miles from HKG! And, about TCAS. Many Asian pilots will not obey the TCAS because ATC told them to do something else, and they do as they are told. When you get an instruction (not an advisory) from the TCAS, it is because ATC has FAILED to keep traffic separated and it is to prevent the ATC failure from killing you. Those clowns just do NOT get it.

Tasić died 20 years ago, quiet young.

[@dusancorlija9088]

Cowboy, you blame YU Government ???🤠

[@duartesimoes508]

Actually, in case of a TCAS alert the only reply from the Controller will precisely be"Roger" and nothing else. I myself was ATCo and was taught that. During the _Resolution Advisory_ the Controller stops controlling both planes involved and will only resume doing so when the pilots report "Clear of Conflict". He is strictly forbidden to transmit further instructions or traffic Information while the RA develops.

Thanks, Chloe, for this comprehensive account of the tragic event. I’m glad that justice eventually prevailed, but I assume that Tasic was a very different man on release in 1978 than he was on the morning of that fateful day in 1976.

While midair collisions are not as common as say 30-40 years ago, there's another one that could be looked on in a future - the Quiberon Bay mid-air collision. One of the planes involved - Proteus Airlines Flight 706, was performing a regional flight from Lyon to Nantes, took a detour at the request of a passenger to view the SS France (a large cruise ship, which at the time of the incident was named SS Norway) which was nearby. After doing a quick tour and on their way back to their original flight course, a Cessna plane struck the Proteus' Beechcraft, killing all people (15 in total - 14 in the Beechcraft and 1 on the Cessna) on board of both planes. After the revelation that a passenger requested the Beechcraft to take a detour in the bay, investigators were shocked. They were also shocked that the ATC allowed them to take said detour.

[@jonfox8010]

That accident has been covered by another video on KZbin I believe It was on the Smithsonian Channel Aiviatio some 5 years ago.

[@jfangm]

The ATC probably didn't know what the detour was for. In all likelihood, the pilot simply requested a temporary course change and the ATC approved it.

[@pla7695]

Such a sad event thank you for the great video as always. Fortunately mid-air collisions are getting increasingly rare due to better technology and improve crew resource management.

[@afreightdogslife]

This is a very sad story of people whose lives were changed forever, with some perishing and some suffering for their loss. The Yugoslavian government was 100% at fault here and not the air traffic controllers. This story reminds me of the tragedy over the German town of Überlingen, where two commercial aircraft collided in midair, a DHL B757 cargo aircraft, and a Bashkirian Airlines TU-154 passenger jet, killing everyone onboard and as a result the air traffic controller was murdered by a family member of one of the victims of the tragedy. It was truly a sad day for all involved. Good video, as always!

[@pooryorick831]

Great video. I was not familiar with this accident. Very informative. I hate it when individual controllers are blamed for these incidents when it is usually a lack of adequate infrastructure and staffing as more and more traffic puts planes in each other's way. As you said, this type of accident is exceedingly rare now. TCAS and other improvements have mitigated most of the risk. But it is horrifying to think about what those people went through up there. RIP.

Good job, thanks for the video. Under staffing is a chronic problem. I was a truck driver with a chronically understaffed dispatch department. As a result I wasted many hours waiting for answers from dispatch. This did not impact safety directly but led to frustration, exhaustion and eventually to me throwing the towel and retiring. And whoever came up with just in time shipping should be put behind bars. The Covid disaster in shipping proves the point.

Thanks for the post. It brought back a lot of memories working as an aircraft dispatcher for BA at Zurich airport.That day I was on late shift commencing at 1500 hours, The unconfirmed reports were verified some short time later. It was very grim. Many of us, me included were crying having interacted frequently with flight and cabin crew. The VIP lounge was raided and more than 1 scotch was downed. Some like Paddy needed no encouragement there. Counselling was unheard of in those days and within an hour, Eric the Duty Officer was telling us to get on with it with the evening Trident to London and the Jo'Berg 747 due in later. That's how it went. A very sad day.

[@SiVlog1989]

I cannot imagine the pain that an air traffic controller would feel knowing that a mid-air collision occurred on their watch. A tragic example of this was the first one i was aware of, the Überlingen mid-air collision between a Boeing 777 DHL cargo plane, flight 611 and a Tupolev TU154M from Russia, chartered from Domdedovo airport to Barcelona, Spain, flight 2937. Due in part to a single controller being on duty, numerous technical problems at the Control centre and differences in interpreting the Traffic Collision Avoidance System (TCAS) between Europe and Russia (in Europe, TCAS overrode what the Controller's instructions said, in Russia, they were told the opposite, to obay the Controller instead of TCAS). Even more tragically, one of the grieving parents who lost their whole family in the crash, hunted down the controller in question and cold-bloodedly murdered the controller in front of their own family, irrationally blaming them alone for the crash.

[@zlatkoreder461]

First of all, congratulations to the authors of this report! Bravo, masterfully done! As an Air Traffic Controller, trainee at the time of the accident, positioned in Zagreb Area Control Centre, I indirectly witnessed the accident the details of are thoroughly covered in this report. In addition to the background of the accident, I’d like to add that Tasic lived in a small building, rather shack, with his family (wife and two small children), at the airport where a middle marker or some other equipment was installed! At that time, many ATCs in Zagreb were originally from Belgrade. They contracted to work in Zagreb where we experienced great difficulties renting accommodation and paying for it as the salaries were insufficient. Knowing those involved (Tasic, Pelin, and Erjavec) very well, it is my opinion that Tasic never issued a clearance to Adria 550 to climb. I believe that Pelin looked at the Tasic’s console, concluded that FL350 was vacant and relayed it to Erjavec. FL350 was available but only after Zagreb VOR! Also, we were trained to ‘stand by’ squawks when transferring aircraft from one sector to another. During that time an aircraft was invisible on the radar screen. This procedure was wrong but we didn’t know at that time! At the end. Tasic was released from prison, separated from his wife and was reemployed by the same ATC company but only as an admin officer. In the meantime, I was transferred to Belgrade ACC in 1983. Very often, in the night shifts, Tasic was coming and sat next to me and we talked few times about accidents. Every time he was very persuasive that he hadn’t approved Adria to climb - and I believe him! All three of them are not between us anymore.

[@twentyrothmans7308]

MacArthur Job covered this in one of his books, and I recommend all of them to those who are interested in this aspect of aviation. His level of detail (as an experienced pilot), is very high, and they're a great read on a flight. It's difficult to understand any criticism of the BA pilots.

It's a fun (because aside from heart palpitations all around, nobody suffered too much) little story about ATC confusion nearly creating a mid-air collision that would've taken out President Eisenhower at the time... bonus for getting to feature a Constellation again... haha... BUT you may need a model for the Lockheed-VC-121A from Eastern that was also "involved"... In any case, it's a little testament to how even just a Call Sign can cause enough miscommunication to create a tragedy if we're not all paying attention and "on the ball" as it were... and the resulting point in History has a few fascinating and fun points following after... Including where "Columbine II", the Constellation in question has ended up "to date"... ;o)

I was ATCo for 31 years, and of course in due time I received a very well written English language description of this accident, that I still own. Its reading is absolutely chilling, much more so to a Controller. I always found this accident exceedingly complex, and keep in mind that what each Controller said to the other in the handover is disputed and will never be ascertained. But indeed, had the Controller not intervened both aircraft would have crossed without hitting each other. Just one remark, the carton flight progression strips were still very much in use in Portugal when I stopped working in 2019, and I can attest that the Air Traffic Services in Portugal are truly excellent, State of the Art in all respects. The strips are being replaced now, but they still have much going for them, being a reliable and inherently simple and instinctive way of controlling aircraft. And anyway, what is used today is a flight progression strip as well, only virtual, in a screen. What has really gone is the carton...

This reminds me of the 2002 Überlingen mid-air collision in south west Germany, next to the Swiss and French border. Both planes were under control of Swiss Guide in Zürich. Both planes had TCAS and had the controller not intervened, the planes would have avoided each other. He was blamed, but the whole situation at Swiss Guide was very bad. And about blaming one person, just recently with the big train crash in Greece, the dispatcher was blamed, where as the train company staff, an dispatchers have been complaining for years about the bad condition of the safety systems on the Greece railways, but nothing happened.

[@ticijevish]

The problem was that the British Airways plane was coming from Adria's left side - but from behind them. Krumpek and Ivanuš had been told of traffic passing ahead of them from their left to their right, so they were probably looking intently at their left side. From either seat in the Adria cockpit, seeing the British Airways plane was literally impossible, as they were coming at them from slightly behind them. (The ending slide after you've seen the video through to the end is a very good illustration of their relative attitudes upon collision). On the other hand, the British Airways pilots had at least ten seconds to spot the Adria coming at them and react accordingly. Allegedly, they were not looking outside at all in those fateful moments. All air accidents happen as a combination of factors, there is very rarely a single cause, or single culprit (like the buttwipe that crashed the Germanwings plane into the French alps). In this tragedy, the general circumstances of aviation were at fault, cause the air traffic over Yugoslavia increased manyfold in just a few years, whilst the corrupt, socialist government of the country couldn't adapt to it in a timely fashion. There was a faulty radar system in play. The controller was overworked, left without assistance and startled after a miscommunication with a colleague suddenly put a plane in his airspace. He did mess up by not giving out a hardier conflict resolution to both planes. There were several seconds of tense waiting, which he could have used to also tell the Brits to climb, that might have woken them up in time to act. The Brittish Airways pilots should have been looking outside their windows. The weather was good and the skies were clear with excellent visibility. There is no one factor which caused this accident, but many that came into a perfect alignment of overwork, miscommunication and negligence. This is why the air travel industry adopts a "no fault" strategy when dealing with disasters. Everyone needs to speak up, everyone's work needs to be scrutinized, everyone needs to keep training and improving and scapegoating is a failure. If the Brits had been attentive - all the faults of the Yugoslav authorities would have been irrelevant as no collision would have occured. If Tasić had give ln proper conflict resolution orders no collision would have occurred. If the middle sector controllers had waited for Tasić to give them their full attention and clearly communicate, the collision would not have occurred. Not to mention if Hochberger had stayed at his post, or if his relief hadn't been late... But, ultimately, the culpability remains at the feet of the Yugoslav authorities as any system dealing with air travel and other matters that have low tolerance for mistakes must be designed in such a way that any one person's failings cannot cause a disaster. We are all human and we are all fallible. And scapegoating only leads to greater misery down the line.
