i got 35 more films for you, i guess you think a lancaster engine needs 10+ 30mm hits to get an oil leak and a b17 wing shouldnt come off under 25x 30mm hits. 
The Bug is almost in all films posted in this thread... Keep saying "no there is not" after every film posted, i guess u got plenty of time to waste, good for you. 
Historically, 3-6(big max)mk108 hits (sprayed on plane whole structure, considering the destruction power of the ammo) were needed to get a b-17 down btw, not 30-60. 
No need for hyperbole, let's look at exactly what you hit there.
First pass: 1 30mm on the bomb bay door. 1 30mm on the engine cowling. 1 30mm on the fuselage near the tail on the first pass. All damage on the left side. High speed.
Second pass: Solid rake down the right side of the fuselage. 3(?) 30mms. Fuel leak on right wing. Medium speed.
Third pass: 1 hit on the right bomb bay door, 1 hit just in front of the tail. Fuselage splits. Multiple solid hits on the right wing, right wing destroyed. Relatively slow.
Now, as you may or may not be aware, different parts on the airplane have their own HP. They all count their damage individually. Explosions are a bit nebulous, but whatever damage is done to a part is done to that part and is unaffected by damage to the surrounding area. The parts are all either working, or not working when they receive enough damage, there's no in between.
So looking at that video, what you basically had was singleton hits to various parts, and the damage that did the plane in was to the rear fuselage, with 4 hits to that part, possibly 5. It's unclear what bomb bay doors count as, but I'd expect them to be part of the front fuselage where the wings attach.
Now, we can grumble about the all or nothing DM if we like, but 5 hits to the large metal tube part of the plane did bring it down, while a bunch of singletons to the wings and engine cowlings didn't. Also, the majority of your hits were at a slower closing speed, which would result in less damage.
What I get the sense is, you guys basically feel anything smaller than a bomber fuselage that gets hit by a single tater under all conditions should be gone, period. Not entirely sure I agree with it from either a gameplay perspective or historical one.
Within the constraints of how the DM works now though, I just don't see anything there that's out of line with the way things currently work. How they should be? Completely different argument, but my point is it doesn't look like a bug.
