This evening I had a hole put in my main tank. All the gas drained out and I was out of fuel. Yes the auxiliary was empty. Shortly there after, I got a little shot up and my main tank caught on fire. So, my point is if the tank was devoid of fuel then how could it catch on fire?
The reason this matters is during the times when you may be within gliding distance of your base. Having a magical fire would prevent you from landing in most cases since it doesn't take that long for the fire to destroy the plane.
Regardless of hypothetical situations, no fuel = no fire. It would be like a gun continuing to fire without bullets. I would appreciate it if this was dealt with.
