this kills the alien. they thought they could come to our earth, blend in with our craft, observe our cities and military bases? for the last hundred years we have been installing secret advanced tech on our aircraft, we call it a "light-emitting diode." any alien fundamentally cannot understand a diode that emits light, if you see a craft with a light-emitting diode on it it means that it's human because aliens could never mimic it, and even if they could they would never ever have any reason ever to even try with such advanced and crazy technology, the amount of effort for them would be too much and they could not justify it logistically.
