They will Probably find that it was a top secret American project that no one else knew about. And they have. Just wasted a few billion in research money.

A normal glider has reached 76,000 feet in altitude, so I imagine a solar powered motor glider could certainly reach 40,000 feet, consuming very little power. Maybe, but by 76000 feet a normal propeller would be suffering from cavitation and the tip speed would be supersonic. Cavitation occurs when a fluids static pressure falls below its vapour pressure, in other words it boils, air, being a gas cannot do that. Whether the tip speed of a propeller is above the local speed of sound would be dependent upon the speed of rotation. Solar powered aircraft have low speed propellers. |

No one would have believed that in the early 2020's human affairs...

There's been more of them. I'm downloading some Slim Whitman records just in case.

Did I hear the small ones are balloons too? Strange shape for one (cylindrical?)

Now they are saying that they (The US) don't know what they were. They could have been gaseous balloons or some sort of propulsion system. And Biden has not ruled out that they are extra-terrestrial. So ET turns up in a non-polluting, environmentally-friendly system, looking for a place to land to say 'Greetings world! look! this is how you do it! We present to you the answer to all your energy needs:) They look for a place to land having prepared the broadcast to the world. 'There's a spot, just down there, press the button...Greetings...oh $hit, what is that F22 doin?'  |

I've just been shopping for canned food and bottled water, just in case. I did wonder about collecting sneezes to chuck at the visitors.

Maybe that was them just saying "Hi". |

I really don't know what all the fuss is about. These things have been around since 'The Prisoner' in 1967, they're just a bit higher up now.
