U.F.O

Unidentified Flying Object (U.F.O), really?

If a military force wants to find out about a place they drop in a recon unit/team/cell whatever you want to call it. They get dropped off far from the “target” area then have to move more often than not covertly into the area and when there operate in the same covert way. They don't fly in front of aircraft or let themselves be seen. No big flashing lights or odd looking shapes. They do their research so they know what looks normal before going in.

If a life form from another planet is able to develop a craft to fly from their planet that is undetectable on R.A.D.A.R, why would they ft big flashing lights to them or lights that don't resemble anything on our planet or give off a sound that we'd recognise? A life form with such great intelligence would surely fit their craft with some sort of noise let/speaker to simulate aircraft noise. They must know we can see their lights due to watching us from a distance that we react to light.

The military investigations are often based on civilian sightings. Why, there for when military aircraft or vessels and weaponry not attempt to take them out of the sky? Yes, a weapon to use costs money but then their would be definitive proof there is at very least one extra life form in the universe other than those that are on earth.

I do believe there is more than likely other life forms out there – but I don't believe they would be so lazy with their covertness.
