It doesn’t happen often, but fuel tanks do explode.

The metal was bent INTO the fuel tank, hence it could not have exploded.
BTW, what color are the clouds in you world?
This isn’t in the same category but similar, my first job out of college was as an engineer for Cessna Wallace. One of the production workers was cleaning a wing with Ketone Acetate and decided to sit down on the wing and have a smoke. The fumes ignited and the wing exploded. The guy was almost picking shrapnel out of his ass. Live and learn.
