Designed and built themselves. Did you miss that part?
No, you missed the history of amateur radio over almost the last century. "Homebrew" equipment is an integral part of it. Hams at the college level were designing equipment, building it, and communicating by bouncing signals off the bleeping MOON fifty years ago.
Only in very cold climates where the naptha keeps it from getting gooey. That stuff, called Jet-B, is widely banned elsewhere because it will ignite too easily in a crash landing. The rest of the civil aviation world uses Jet-A (in the USA) and Jet-A1 (elsewhere). Apart from having the solid crap filtered out of it, and some microorganism and corrosion inhibitors added, it's plain old kerosene -- your grandfather's coal oil.
OK, so you want to maintain scientoideological purity and claim "heavy" only has to do with gravity...so what? Two kilograms is still heavier than one kilogram, no matter what gravity you apply to them.
The airline already apologized, refunded the money, and paid for the other flight the family took that trip.
...which is precisely what the airline is required to do by the denied-boarding rules. These rules were meant to deal with overbooked flights, but since the FBI cleared the family, I doubt the airline would have much of a leg to stand on if they tried to refuse payment.
There's also a theorized seasonal component caused by sap rising and leaves growing in trees in alternate hemispheres, but that's pretty well down in the noise.
How would you know that? Meteors that are big enough to reach the ground are seldom glowing when they do; once the upper atmosphere has slowed them down, the long fall through the lower atmosphere cools them off. They hit the ground pretty hot, but almost never glowing.
As far as satellite launching is concerned, the height of the launch site is utterly trivial. In order to achieve a low earth orbit, you have to accelerate an object to about 23,000 feet per second; for a one-pound object, that will take over 8 million foot-pounds of energy. Lifting that same object from sea level to the top of Mt. Everest will take 29,029 foot-pounds.
The latitude of the launch site offers some tradeoffs. A site on the equator will give you a few hundred extra feet per second than one at 45 degrees latitude, not a real big advantage. However, a launch directly into orbit will always put you in an orbit whose inclination is at least the latitude of the launch site. Launch from Cape Canaveral, and you'll be in an orbit inclined at least 28 degrees from the equator. You can make it higher, but not lower. If you want to get an equatorial orbit -- which most communications birds need -- you have to launch into the inclined orbit first, fly to the equatorial plane, and then make a "plane change" maneuver which takes a substantial fraction of the energy it took to put you in orbit. From the equator, you can launch directly into any inclination, which is why the European Space Agency birds come out of French Guiana.
until the Earth stops rocking back-and-forth relative toward the Moon (as the Moon still does a little bit relative to the Earth)
The libration of the Moon is not a rocking motion. It's almost entirely a perspective effect caused by, in descending importance:
1) Eccentricity of the Moon's orbit. It spins at an essentially constant rate, but it does not move round the Earth at a constant rate.
2) Inclination of the Moon's spin axis. It's not parallel to the Earth's axis; when it tilts toward us we see the north polar regions, and two weeks later we see the south end.
3) Rotation of the Earth. Look at the Moon now and again twelve hours from now, and you'll be looking from two places up to eight thousand miles apart.
Maybe they're channeling Jeff Foxworthy. A recent contestant on his program "Are You Smarter Than A Fifth Grader?" was asked "How many watts are there in a kilowatt-hour?" I don't remember any other time when I really wished I was on TV...

Yet. Have you noticed that no UAV has been designed for dogfighting yet?

A data acquisition/display issue.
And no human can withstand as much turning acceleration as a UAV can.

Of course they are. But "more mass" implies "heavier" just as much as "more weight" does!
