I know one time while I was still a bomb loader in the AF (knees got messed up and medically crosstrained) we dropped 3 500 pounders from about 3 feet. EVERYBODY took off running. WHY? Couldn't run far enough fast enough. We just scratched our heads, put them back up, got them to show safe load (again) and this time they stayed.
