How much C4 would it take to depressurize a plane? If I've learned anything from the Die Hard movies, not very much.</font>
A couple of pounds of C-4 would pretty much ensure that any plane is completely destroyed. I believe that the 747 taken down at Lockerbie was destroyed by C-4 that was placed in a radio.
