I have been occasionally distressed in watching action films on TV to see gunfights on airplanes. I assumed that the bullets piercing the airliner hull would result in immediate decompression catastrophe. It never happens.
I learned why, at a gun training session where I was introduced to Glaser bullets.
Invented in the late 1970’s specifically to deal with the air marshall problem of shooting while on an airplane, the Glaser bullets tear a big hole in the first object they hit but don’t go any further. So they won’t hurt the airline skin if they hit something like a person first.
If they miss a person, they may stop after damaging the inner airliner skin.
I also learned from a European airline maintenance inspector at breakfast in a Tokyo hotel that modern airliners burn rather than rip. I don’t know what relevance that has.
Do all the bad guys in the world know about Glaser bullets, or are they just willing to die for their cause whatever it is?
P.S. Done on an IPad so the layout is still not the way I want it.
