The project "Grab Bag" ("Bag") was a program of sampling of the air, conducted by the United States from 1956 to the early 70-ies of the monitoring in the stratosphere of above-ground testing of nuclear weapons in the Soviet Union.
Special equipment mounted on a balloon, took samples of stratospheric air were pumped into a special container powerful pump. At some point the ball down from the height of 20 to 30 kilometers to one or two and dropped by parachute hardware that the flight was intercepted by a spy plane, and the balloon, freed from the burden, moved up and somewhere in the stratosphere burst. Debris such balls later fell to the ground and sometimes taken for the remains of alien ships.
I wonder what getting parts collected radioactive materials on the ground gave rise to the idea of mandatory increase in the radioactivity of the landing site of a UFO.
