well what i mean is maybe a airplane sent off a message over shortwave
radio lets say back in 1940 and maybe just now from 1990 on to 2004
maybe u heard the message over ur radio , and found out it was from a
plane or something else in a back farther date over shortwave.

There have been documented cases of this happening, so nobody should start
riduculing you. There was a case in Britain of a several years old TV
broadcast being received by a number of people.

Just like light, radio transmissions never stop. They are diminished and
absorbed by the atmosphere, but those that have escaped Earth continue to
travel through space at the speed of light. If somehow they were reflected
back to Earth, it would be perfectly possible to receive them years later.
