Help me please as I'm not a native speaker and cannot comprehend the idea behind this name.
The "pickle-barrel" bombing was (I'm quoting from WWII Ace Stories site):
"Pickle Barrel Bombing was a spin-off from a new radar system, touted to be accurate within fifty feet from a distance of fifty miles. They thought the idea was simple. Send a bunch of P-47s out over solid cloud cover at 10,000 ft. and 250 mph. in tight formation. Guide them to the target with the new radar, and tell them exactly when to drop their bombs".
I know what a "pickle" is, and I imagine you can store them in a "barrel", but how it relates to a radar-control bombing is beyond my imagination
