Say a word about this over the radio, and the next wings you see will belong to the flies buzzing over your rotting corpse!

Our reading
An editorial interpretation.
A menacing threat to keep quiet: if the listener reports this over the radio, the only wings they'll see afterward will be on flies swarming their dead body. It's a grisly, theatrical way of saying silence is mandatory, twisting the idea of wings into a vivid, gross image.
