Every time a new video by Allec shows up on my feed I press the like button before I view it because I always know it will be top notch

[@phantomf4747]

100% concur

[@JaymesEaston]

I really like this one. The photos of the re-constructed aircraft debris, the crash, the aircrew's actions that puts it into perspective.

[@JasonMcCord-qk3yb]

Awesome video, as always. So, in a nutshell: The NTSB didn’t really know the cause, but had to go with a “Most-likely” explanation. That couldn’t have went over well with a lot of the investigators. Having worked alongside them a few times (I was an ‘Oversized Loads’ mover/driver; Who better to transport large pieces of an aircraft!) I know they are OBSESSIVE in just about anything they do. It’s what makes them the best accident investigations branch in the world.

[@Houndini]

All investigation agencies from our govt. is famous for spreading the blame out as far as possible.

[@TheShowblox]

That livery is so simple, but damn is it CLEAN AF🔥🔥🔥 Especially on the DC-9!

[@TheFatNumpty]

Pity the wings weren’t

[@Supersean0001]

This was always a problem on the -10 Series DC-9s, which, unlike the subsequent versions of the DC-9/MD-80, had a "hard" wing leading edge -- one with no slats. There were a rash of accidents back in the 1980s involving crews that forgot to extend the slats (and flaps) for takeoff and then had major control issues after barely getting the plane off the ground. Extending the slats has a MUCH greater effect on lowering stall speed and enhancing controllability at lower speeds, than extending the flaps. The only time I'm a nervous flier is on the smaller airliners with no leading edge slats in the winter -- because of this issue.

[@ThisHandleFeatureIsStupid]

Haha. Accidental strikethrough. 😆

[@kcindc5539]

When it confirmed my suspicion the DC-9 was a -15 my first thought was “ice contamination”. The series -15 aircraft did not have leading edge slats (just like the equally problematic Fokker F-28 series), making them that much more sensitive to even minute amounts of wing contamination. The 1987 Continental DC-9 crash in Denver, and the 1992 USAir F-28 crash at LaGuardia experienced a similar sequence of events with similar outcomes. Both of the latter aircraft had been de-iced, however both remained on the ground long enough after de-icing for it to lose effectiveness and contamination to occur. Other aircraft in Denver and LaGuardia at the time of the crashes no doubt experienced similar losses of de-icing effectiveness, but all other domestic jet transport aircraft in service at those times were equipped with leading edge high lift devices. The only jet transport aircraft in commercial service lacking leading edge slats at those times were the DC-9 Series-15 and the Fokker F-28. RIP

Your comment mirrors almost exactly what I was going to post. I'm glad that I scrolled down and read some comments. Yours hit the nail right on the head. Additionally, though not relevant to this accident, the lack of slats lengthened floats during landing. Slats along with the flaps increase lift at a given airspeed, but they also cause drag. Slat-less A/C, lacking that drag, bleed off airspeed in the flair more slowly increasing the propensity to float on landing.

[@kcindc5539]

@ a double-whammy for an aircraft specifically intended for use on shorter runways…. especially those in northern climates.

[@paulw4310]

@@kcindc5539 Exactly.👍

[@Eric-gj6uf]

So then, is this also a problem for the CRJ-200? If memory serve me correctly, that aircraft also does not have leading edge slats.

[@kcindc5539]

@ good question. The answer is “not necessarily”. The good news is that in the years following the era of those crashes, several new requirements, from the precise chemical formulation of de-icing fluids to strict adherence to ground duration limits post de-icing, to advancements in aircraft design (including, among other things, more effective wing anti-ice prevention), to collective lowering of atmospheric thresholds to present departures in previously allowable conditions, have effectively eliminated the incidence of wing contamination stalls on takeoff among commercial passenger jet transport operating in North America. Even the infamous “Palm 90” 737-200 crash in 1982 helped reduce such accidents among similarly designed aircraft (in that particular crash there were several root causes - none specifically related to the existence of leading edge slats which were deployed on that aircraft).

[@WendyKS93]

Mr. Allec, I hope you and your loved ones have a beautiful and happy holiday season and a very safe one. Thank you for all your great videos, they are so interesting and informative.

[@Jayden-rn3gn]

Great new video😊

[@baraxor]

When I see it snowing, however lightly, my first thought is icing conditions, especially if this isn't discussed between the pilots in the re-enactment.

[@vfx7t]

The majority of you often wonder about the reasons behind these plane crashes while watching the videos. As for me, I always think about the families of the victims of these tragedies, RIP !!

[@horseathalt7308]

I think of both. I'm sure there are still immediate family members that are still missing them today.

[@ABYStheOyster]

I miss that old USPS logo. As a young kid, I thought it was a silhouette of a cartoon man, carrying a package under his arm, like a deliveryman. The new logo is more unmistakably an eagle so not nearly as easy to interpret differently.

[@mikewhipkey6863]

Me to I thought I was the only one

[@dx1450]

I don't see it. I just see an eagle.

[@FH99]

You would think that information would have been passed along when Ryan International Airlines acquired the plane, so the pilots would know about the possibility of this.

[@Houndini]

Sure appears there top pilot would know all their planes top to bottom . I don’t know on this deal but a lot of this type of issues the root cause come straight back to management cost cutting decisions. But sadly if you want to keep your job you never bring that up to The Management.

[@asssfukcocsukmotherf]

have to blame ryan international airlines for not doing history checks on the planes they bought and flying....if you buy a used car you do research on it don't you? i guess there was no common sence in management for that company

[@6omega2]

The minute I saw "February" and "Cleveland," I thought to myself, "I'll bet this will be about rime icing." Sure enough...

[@doriangray2020]

Ha! Sure you did.

[@jyralnadreth4442]

Condolences to the familys....at least this happened on a cargo flight rather than a passenger flight. It shouldn't happen at all and should be covered in the flight manual...they should add the bulletin's about the aircraft in the thing.

[@glamdolly30]

How often tragedies occur due only to poor communication!

[@ewrcap]

Almost identical to the Continental 1713 crash at DEN a few years earlier as well as two FokkerF28 crashes in icing conditions. All of these lacked leading edge devices.

[@thomashutchins240]

Can you do the Blue Angles accident from 2007 and 2016?

[@gwm08]

Maybe do Pulkovo flight 612

[@TheShowblox]

SWISSAIR 306 WHEN😭💀🙏🏻

[@StephenLuke]

As well as China Airlines 611, Air India 182, LAM Mozambique 470, Korean 858, TWA 3, JFK Jr., you name it.

[@alphredluneomax93]

​@@StephenLukesame here I was waiting for China Airlines 611 Air india 182 and LAM 470

[@bradjohnson482]

Maybe he doesn't have the time for longer videos these days?

[@muhammadfaridsuryautama319]

The flight was originated in Buffalo New York

[@roberthagedorn290]

That's interesting. Buffalo has some of the worst winter weather in the world. Maybe after dealing with Buffalo weather the pilots got overconfident and underestimated Cleveland's horrible weather.

[@TheShowblox]

Wait, there’s more than one “Ryan” airline?!?

[@quangminhnguyen2504]

The aviation is truly full of mystery

[@KenH737]

Not to be confused with Ryanair which is a low cost European carrier based in Ireland. Ryan International went out of business years ago.

[@MykelBBY1]

The USPS flies planes like they deliver mail.

[@dinorosga9147]

So was ice the problem then?

[@bobhead6243]

😊👍🙏

[@grimson]

Just one fan asking you to stop spoiling the outcome with these thumbnails.

[@lohrtom]

Was the aircraft repaired and returned to service?

[@GalootWrangler]

“Destroyed, written off” according to Aviation Safety Network.

[@bullseyes1983]

As usual, MD planes were shit.

[@robs5688]

In those days, if your main competitor was Boeing, you cut costs in wing design to remain competitive. 😉

[@frankblangeard8865]

When a plane is too old to fly safely it is made into a cargo plane.

[@flyingattheforest]

Your old videos was better

[@horseathalt7308]

He's a busy guy, and he is a commercial pilot too.

[@bobbycv64]

I wish you would monetize your site, would like to support your channel, no through the old Patreon system. Your videos are wonderful, Thanks
