So applying the same logic what about all of the unknowns that have been spotted on radar?
If there was a radar return then the microwaves hit the object and scattered, why didn’t these UFOs fail?
Operation Charlie instantly springs to mind as this occurred in 1947 when the UK’s east coast radar defences were triggered several times by mysterious intrusions. RAF interceptors were launched and picked up the UFOs on airborne radar too, but that was as close as they ever got.
Why didn’t those UFOs suffer from what could be considered a multiple radar ‘attack’?
