For the United States, there is a an easy 20 question quiz that is called "The World's Smallest Political Quiz. http://www.self-gov.org/quiz.html".
Two million people have taken the quiz and sometimes the results are quite shocking for the test taker.
Gravity is indeed the opposite force involved. But the higher the air pressure the denser the air. The denser the air the easier it is to float.
Think of how much easier it is to float in sea water than in fresh water. Same difference with air.
In Levenspiel's paper, he has several graphs of the power needed to keep everything from a gnat to 747 in the air. Also what power is available from creatures as small as a mouse to as large as an elephant.
When the curves are solved, the answer is air that is four times denser than what we have now.
Also, with the higher air pressure the column of liquid that is supported by the atmosphere is higher, which lets the creatures have very long necks and still keep blood going to their brains.
I attended a lecture of Dr. Octave Levenspiel a few years back where he had solved the riddle of how something that big could fly.
It's called air pressure.
For anything to fly that is that big, he showed that the air pressure had to be four times what it is today. Here's a link to his paper.
It also explains why dinosaurs could have such long necks and not pass out from loss of blood to their brains.
My dad used to do tech service on the Univac in Kansas City at the USDA building. (It took an entire building to just hold the computer.)
One Christmas he took me on a tour of the computer. They had programmed the different pieces of equipment to make their distinct noises to play Christmas Carols.
Also got a real tour of the computer - from the inside. We walked through one area where I was told that if I tripped, to grab a cable that would cut the power to the computer to keep from get electricuted when I hit the tubes.
All in all a pretty fascinating tour,

I've learned the the most common second language isn't English ... but bad English.
I think the liquid metal is their server.
That would only explain a delay of a minute or two.

Why read how the 2nd place finishers did?
Here's the article that should have been posted (from the winners) and with pictures and tactics.

Great and really interesting paper.
