Theodor Weissenberger's BF-109: Restoration of a Wreck Recovery at Pima Air and Space Museum

[@powerjets3512]

Wow. This guy not only knows his plane, but equally impressive he explains it so well in such a logical fashion.

[@oldgoat142]

Sofi taking me on a virtual trip through an aviation museum is a delightful way to spend some time. 33 minutes of fun! You're a great content creator, Sofi. You ask a question, and allow the person to answer fully without interruption. I personally greatly appreciate it.

Some error corrections: The F-Model was the first major overhaul of the design - a new Wing was designed with rounded tips and much improved aircooler installation - now automaticly regulated. The basic armament changed fundamentally from 2 x 7.8mm MG17 in the engine cowl + 2 x 20 mm MG/FF in the wings to a single although more potent MG151 either in the 20mm or 15mm configuration firing through the prop-hub and the 2 x 7.8mm MG17.in the cowl. The oiltank was moved from under the front cockpit cover (right behind and slightly below the instrument panel) to the place where the watertank had been in the prior versions behind prop-spinner, while the watertank was split into two and placed on each side of the crankcase - also the propblades were now changed in incidence via an automatic circuitry (with manual as an option). It's being said that you need around 1 million $ to get an airworthy airframe (wings, cockpit, tail) - without an engine and all the other stuff - of which there is plenty. To get it into a Flyer add another 1.5 Mio. atleast.

[@bigsarge2085]

[@johnbrooks1269]

"American military history researcher" extraordinaire is the apt description for this lovely young lady. Sofilein I do so enjoy your videos and your dedication to the viewers. Pima ASM might benefit from a dedicated 3D printer. Sections that are hidden (under a cowling for instance) and once held parts subsequently lost could be replicated and exposed on demand. The manner in which you allow/encourage a museums spokesperson is rare and oh so excellent. Thanks for sharing. Cheers! 🤠

[@rc166honda]

Genuinely that was absolutely fascinating, many thanks for posting.

[@trespire]

Great to see Sofi again. As an Ex F-4E (Kurnass) maintainer I'm happy you're touching on other aspects such as air power. Ground attack jets and fast propellor powered planes can have a huge punch, even with "smaller" 30 to 40mm caliber. It's the added ground speed that increases the kinetic punch at a square ratio ( K = ( m x V^2) / 4 ). (sorry for the equation) Late WW2 panes, when attacking in a dive were flying close to Mach-1. Todays jets still attack at the same speeds. The BF-109 was a force to reckon with, even for MBT and heavy armour.

[@easynovember5423]

Thanks!

[@Terry_Fritz]

Sofilien; you are an amazing presenter. You ask a question and then allow people to say what they want to tell us without trying to make it into 30 second sound bytes for the attention challenged by interrupting. I tip my hat to you. 🦘

[@fatcat3211]

What a rare aircraft. Usually you see Spanish Buchons being restored.

[@samuraijaydee]

I Love that today we colaberate over these aircraft, rather than fight to the death with them.

[@seanmalloy7249]

9:55 If I remember the situation correctly, the Bf109s could simply push over into a dive, and their fuel-injection system would keep fuel flowing to the engine; if a Spitfire or Hurricane tried the same maneuver, it would lift the float in the carburetor and starve the engine. To prevent this, Spitfire and Hurricane pilots would have to roll inverted so as to maintain positive G loads on the air frame as they followed the Bf109 down, and during the time it took them to roll inverted, they could lose sight of the German plane if it maneuvered appropriately.

[@Manta-82]

[@marknelson5929]

The Bf 109 E (Emil) never went into service with an engine mounted cannon in your intro. It was tested with them but vibration precluded its use. The cannon first saw use in your F model after the issues had been resolved. Alongside the altered tail unit you mentioned on the F model, this aircraft also had a completely new wing design which precluded internal wing mounted armament like in the E model. Lastly from the cockpit forward the whole cowling, spinner and oil cooler fairing was much more streamlined. Some say the F model was the best balance between weight and handling - creating a lovely aircraft to fly. As from the G model onwards, increased weight etc affected the handling. Good to see an F model being restored, they are relatively rare survivors.

[@briancox2721]

What our museum friend said about the cowling interchangeability still applies today. I was involved in a project about ten years ago to improve the as built shape of a body panel for the F-35. The previous supplier was so off that each one had to be modified, tweeked, shimmed, and forced to fit each aircraft. When we were done, the part was replaceable and interchangeable rated, meaning you could take a replacement panel off the shelf and it would fit without modification, and you could swap panels between aircraft without modification.

[@Octopootie1]

Nice! The 109 is my favorite aircraft I look forward to this projects completion. Just one little autistic nitpick about the basic facts on the F-4 stated at the beginning. The armament was not unchanged from previous versions. One of the main changes of the F-4 from the F-2 was replacing the 15mm MG 151/15 nose cannon in the F-2, to the 20mm MG 151/20. The wing mounted 20mm cannons in the earlier "E" 109's used MG FF's, which had a slower RoF and muzzle velocity than the MG 151/20.

[@dagabbagool2600]

I have thousands of nerd hours piloting 109s across multiple WW2 combat flight sims and the Friedrich was always my favorite, by far. A good bit faster than the Emil, and a good bit lighter and more maneuverable than the Gustav. It's the perfect combination of speed, instantaneous and sustained turn rate, and climb rate. I've built my own ultralight and it's truly a bucket list dream to build, or really just fly any variant of the 109, real or reproduction. Maybe in 30 years it'll be possible to 3D print one!

[@U812-k7j]

[@Stray03]

I enjoy listening to people who are "overburdened" with knowledge on subjects (Why I like listening to museum volunteers, and some private collectors), they always take tangents on subjects adding that little bit of extra interesting information that otherwise would just be a copy paste history channel style explanation.

[@vonWeizhacker69]

what does a fokker do..?

[@thkempe]

​@@vonWeizhacker69 Anthony Fokker was a Dutchman. In contrast to Messerschmitt, his family name does not describe a profession. Fokker/Focker comes from the old first name Folkhard, which means Volk/folk + hart/hard. A similar traditional German name would be Volker, but people in Germany no longer use traditional names. Btw, the former president of the German Federal Republic whose picture you are using, is spelled Weizsäcker (wheat + sack).

[@vonWeizhacker69]

@@thkempe Thank you, very informative. I bet you're great at any party. ;)

[@happyhome41]

Wonderful video !

[@Mitchell_Gant]

The F-4 is probably the pinnacle of the Bf-109s, and it also fought in the last glory days of the Luftwaffe. Weissenberger's story is also interesting, started out with the Bf-110 heavy fighter and was successful with it despite the bad reputation that plane gets. After the Eastern front, he fights over France in the post D-Day period, which campaigns are infamous for the Luftwaffe being almost nonexistent due to the enormous USAAF/RAF air superiority, nevertheless he does well against the american and british fighters and fighter-bombers here too.

[@jackharris4697]

Your doing a wonderful job , with so much effort into bringing it back only for a static model just seem wrong . As you stated parts a there so why no go all the way ?.

[@aceshigh6499]

These aircraft are extremely challenging to land.

[@matthewpayne42]

So is the Spitfire.

[@Sofilein]

I drive on the ground so ngl all aircraft sound challenging to land, to me 😂

[@Triple_J.1]

The BF-109 landing gear is "splayed" at an angle. Just like rolling a tire that is leaning to one side, this causes it to turn. When both landing gear are splayed like this, they both try to steer -away- -from- *toward* the centerline. If you put more weight on one, it will swerve the other direction. When it swerves, then it leans harder yet on that side, and it swerves harder. This in addition to the fact the center of gravity (mass centroid) of the aircraft is behind the main landing gear. This exacerbates the swerving tendency, as the weight is located behind the tire contact patches and continues to diverge. With enough side-load, the gear snaps off. Ruining the propeller and engine. Damaging the airframe. Possibly injuring the pilot or even flipping over and lighting afire. I've heard that this was the most produced aircraft in history. And fully 1/3rd of the were destroyed in accidents. The Spitfire was EASY to land. Comparatively. Its landing gear is narrow, sure. But it does not diverge. All pilot accounts said the Spitfire was easy to land. And accident data shows it was at least 5x easier to land than the BF-109. A flight instructor of mine who had an opportunity to fly a spitfire, and a P-51. AND a BF-109 said the Spit was "easy" it "flew like a general aviation aircraft. Any pilot can fly it" to the P-51 "high wing-loading, sharp stall" to the Bf-109 "It's entirely a different animal. It cant be compared to Spitfire, or P-40" (another narrow gear plane of the era).

[@davidfreiboth1360]

The primary reason for the "inboard" landing gear was to facilitate transportation by trucks over the road network. With the wings off the width of the unit easily towed bahind a truck. This turned out to be a solution looking for a problem as this form of gransporation was rare although rail transportation was likely a bit easier.

[@timhullfilms]

I was looking into this Bf 109 a few years ago for use in my film (set in North Africa, 1943) but it wasn't very far along, so I forgot about it. Doesn't look like they have had much progress on it... I remember seeing photos in this exact state.

[@chickenfishhybrid44]

On the subject of fuel injection, most US fighters by the time they would come into contact with the Germans pretty much all had pressure carbs, did they not? In which case, fuel starvation, etc is not an issue. It was the Brits that had particular issues since they were running standard carbs. They did come up with the quick, easy bandaid piece to add to the carb that helped a lot, but still wasn't a pressure carb or fuel injection.

[@valleywoodstudio7345]

I remember as a kid being told by a restorer on HMS Victory in Portsmouth, that if a new part occupied the same space as the original (such as a piece of rotten wood cut out and replaced with new) it was deemed "authentic".

I'd argue that the Buchons are indeed 109s. Yes, they weren't built by Messerschmitt and they don't have Daimler Bernz engines, but 109s built by Messerschmitt used a variety of engines too. The prototype flew with a Rolls Royce Kestrel. The A to D models had Junkers engines. And not all "Messerschmitt" 109s were built by Messerschmitt themselves. Quite a few were built by contractors, such as Erla. And the Buchon was built by Hispano Aviacion, not CASA.
