The secret services supposably posses and can succesfully use "cloaking devices" on craft.
i looked into it and there were 3 authentic cases of civilians spotting f-22s fly through the air. they r sure it was a regular standard aircraft. they see the craft fly, but the disappers into thin air. they could still see the afterburner on the jet; they could even hear it, loud and clear. these cases happend near area 51 (only 2 cases were) and then another case in area 52 in wyoming. in the case in wyoming, the craft appeard to b pursuing a UFO. do you believe that the USA has the ability to cloak devices? yes/no explain
