Estimate of warhead location when fragmented
from my armchair and looking at the photos of cockpit frames AND the photo of a wing segment which shows the red circled ' attach safety line here" with apparently skidding type penetrations by shrapnel - a guess would be the detonation took place slightly above or at the level the upper wing surface. This would seem to comport with some comments that the BUC is designed to hit from above. Had it been on its way up and exploded below the wing level, its a bit unlikely to have shrapnel skid along the upper surface . Safety lines are not usually attached below the wing .
