Gee, I dunno, but a hundred-pound (?) very heavy projectile moving at the speed of sound impacting with ANY part of a plane is going to rip the frakking thing in half. If a .32 can put a hole in a plank, and a .45 can blow the plank off the wall of the barn, think about the 88mm (8.8cm, about 3 and 1/3 inches radius) isn't just going to make a hole and pass through. If it hits ANYwhere it's going to rip whatever it hit straight off. If it hits anywhere on the fuselage it's going to either crack it in half or blow the engine out the other side of the airframe.
Doesn't matter if it's AP. Doesn't matter if it actually explodes or not. That plane should have been totalled.
