B17 crashed

[JG52Krupi]

There was smoke trailing from the aircraft apparently, this doesn't mean that it spread from the engine it could easily have been a fuse box something similar to the one that gutted a 787 during flight test.

You have to remember that these are old aircraft and are made with aluminium that catches fire and burns easily, I don't think that current aluminium alloy aircraft would burn quite that quickly.

That one B-29 which was recovered from ice also went up in flames, those 4 engined birds seem to attract fire.

I cant think of many "fuse boxes" in the wing of a B-17,if there was an electrical fire it would have spreaded in the fuselage,but then again with 7 people on board I reckon that they would have been able to put the fire down..

It could have been a supercharger failure,which might have caused a fire under the wing (hence the visibility from below and the ineffective fire extinguisher procedure). I suppose we will have to wait for the CAA report.

Uh and aluminium pretty much burns in the same way,no matter how old (plus bear in mind that most of these birds are re-skinned).

What a terrible loss! Very fortunate that all on board were able to escape basically uninjured as far as I know.

There was a fire in the wing well behind the inboard starboard engine (photos on line). Supposedly the a/c had been grounded to fix a leaking fuel tank. Used some epoxy to fix the leak, so I would say the epoxy let go and the leaking fuel caught fire.

Been informed that the head of maintenance of the a/c is borderline incompetent.

On the old side of things i wasn't referring to the actual age of the material but the type of aluminium used, aluminum has come a long way since the types/alloys that were first being used on aircraft.

yep, no matter what kind of alloy, it still burns darn quick once ignited

that's a lot of speculation and I somehow doubt that the head of maintenance would be an incompetent guy, the plane has been flying for many years and nobody would put the maintenance of such a machine in the hands of someone who's not up to the job.. Again, let's wait for the CAA report on the accident..

Slightly OT:

On this forum i did hear that the aluminium that the germans used was inferior to that used by the allies, it would be nice to see the material specs and compare them (damn it engineering is supposed to be my job not my hobby ).

[Al Schlageter]

No speculation on the a/c as the a/c had been grounded on the weekend for some kind of maintenance. The a/c exploded in flames after touch down which would happen with no air flow. Gee, just what fuel does.

The comment on the head of maintenance was made by a guy that restores a/c.

Good to see the crew got out okay.
There will be a lot of engineers sweating now waiting for the investigation- the civil aviation guys are very thorough, and that looks like a grease monkey did something they shouldn't or missed something they should have seen.

I say keep 'em flying. There's nothing to compare with seeing these static objects become flying machines again. Accidents will happen, it's a statistical fact, but they can be rebuilt.

yeah, that's the typical hangar bitching, as soon as something goes wrong people start talking $hit about others.. seen it happen before..

Let's look at FACTS: here is a dramatic photo sequence of the fire:

as you can see they managed to land the plane properly, and the fire is on the engine 2 area. If you look closer the prop of engine 2 is actually feathered, which means that it's likely the engine and/or supercharger are at the base of the fire.

Once the fire was out of control, all they could do was look at the plane torching away
