And you would be claiming that these "official secret" adversary aircraft
have "silent sentry"..?

Silent Sentry an airborne system? I did not know that.Anyway thats a big chance
for you to become a very rich person.
Just send your airborne silent sentry proposal to Phillips labs,they trying to
develop an airborne (UCAV) for Air Force.
I am sure they will appreciate your help.

Good Luck
