Online if you blow up a 109's fuel tank, they will run out of fuel within a minute or less and the engine will stop. In a few cases, I have seen where the fire spreads to the cockpit area and the pilot is forced to bail or die.

I have seen the same thing occur with Hurricane wing tanks. Large explosion, plane continues on.

It's a bug. The fuel tank "explodes" but doesn't damage the aircraft.

well at least its been noted...

its funny now, but i was absolutely crushed and shocked after the first time it happened.. I was so thrilled at my apparent 'skilled' deflection shot, only to be completely dumbfounded to see the 109 wheeling back around to get on my six after I banked away

The first time it happened to me I saw "Fuel tank: exploded" come up on the HUD and fire everywhere, so I bailed out ASAP.

From external view I could see my 109 keep flying away, relatively unscathed.

A previous poster was correct though, when he said that the 109 will run out of fuel in very short order. Over England, I'd bet against him getting back to France, even with a full tank.

I think either the fireball is wrongly depicted because tank did not explode but just was damaged. Or the damage model is not right. If it explodes it should make a big hole or even ripp of large chunks of the plane.

BTW: Are there by chance planes that do not explode at all?

If the 109 tank is indeed exploding as the animation would suggest it should result in death or severe burns since the pilot is sitting on the tank. Maybe the seat armor redirects some of the blast outwards but the pilot would surely feel the need to exit immediately.

It is laughable how often the wing tanks on any of the blue bombers explode and rip the wing off at the engine. That has to be the most common method of bomber destruction when I fly red. However, it is few and far between that an engine catches fire, seems it should be the other way around.

The flight and damage models are just borked in a general sense.

I was saying in another thread that it's trivially easy to de-wing a Blenheim. No cannon required.

i think that in itself is a bug. fuel tank explosions are EXTREMELY rare. Because certain conditions must exist for explosive combustion inside a tank. Generally With a tank full, It will not happen. Sure, It will Burn like heck but it won't go boom, because fuel in itself does not explode, but the VAPOR does. Hence why if there is little to no vapor it will not burn. Gasoline, for example in it's purely liquid state does not burn, however the Fumes evaporating do, and burn very well they do. But burning does not equal an explosion. Even when an incendiary bullet or heat source enters the tank, there is a very small and fleeting window (trust me NASA didn't even know for sure when they researched if for the TWA flight 800 explosion) where the tank has the proper vapor pressure, volume, heat and fuel to air mixture to detonate.

As far as I can tell for their reports this combination of events must happen:
-Tank must be nearly empty
-Tank must be heated
-Tank must have proper Fuel/Air Ratio
-Tank must have the proper pressure
-Tank must be exposed to a properly powerful ignition source

All these add up to a pretty specific and rare event.

gimpy: I agree!

Exploding aircraft may not have been something impossible but it surely was a rare event.

As gimpy explained the window for explosion has to be met and this window is considerably smaller than the window for explosion.

Please don't believe Hollywood.

^THIS....

that is something i was also thinking, tho mostly because the fuel tank explosion happens pretty frequently and 'early' in the plane's progression of damage... usually i get coolant punctures with the first couple seconds worth of bullet strikes... its in the next seconds worth that usually triggers the explosion...

unless im fairly accurate at hitting the cockpit area of the fuselage (which im most likely not ) then the total destruction of the fuel tank is definitely too easy to damage.

One other thing... If the tank does explode wouldnt the force of the explosion sever some if not all control cables? Im pretty certain that it would cut the cables goin back into the tail section (rudder and elevators). because right now other thank looking pretty, it has no secondary consequence
