Yes, we were looking for any and all things entering the airspace during the cold war. No, WW2 radar couldn’t see that far up as it was a recent innovation but it was used for the same purpose - to track for any and all entry into the airspace and to serve as an early warning.
Funny how, this weekend, we don’t seem to be having problems “finding” objects with radar and tracking system technology we don’t have, hmmm?
Sigh.They just rewrote some of the software so they could pick those things out both in real time and from past recordings. There was no apparent need before.
stop with the tinfoil.
