LOL! I remember guys walking out in full Bio gear to deal with firing an EPU, but for some reason smarty pants weapons guys that put dummy nose fuses on 500lb bombs and "let them spin" were never brought to justice....it was, however, a good way to make sure pilots went through their entire pre-flight checklist......
My favorite was to create a Mk 82 one lugger and leave the 904 spinning in the breeeze and send out a new crew chief and watch the fun !
A bottle of vinegar poured over a pile of dry ice chips under that epu port was also a hoot !
Yeah I was a funny guy when we had tests for EOD responses !
