Real pilots leave their engines on the ground!!!
PS Ex and present fighter pilots will blow my butt out of the air if they can see me. I am all plastic and if they can not see me with their eyes the sure as hell can not see me with their electronics, and I also only fly below 60 knots. That is a threat category that is not even a threat in their algorithms on their computers.
In an asymmetric warfare I would be and extreme threat in the sky with a relative unsophisticated plastic glider. I could deliver 200 kilograms of anything 200 miles inside of the United States Borders in a Glider that is virtually undetectable on radar. All you need to do is tow my glider to 25000 feet and I am good for in excess of 200 miles. Considering air speed at altitudes in the thinner air, the real intrusion would be about 300 nautical miles which is about 350 statute miles.
OK, well, maybe you can do some stealth work for the Trump Administration against the Skinnies.
