I cant say much about sport. All sport is flying around for the fun of it. A few loops and figure eights and maybe a bit of combat but not in competitions and not really seriously.
One exciting looking thing that sport flyers do if they want to ruin
a few planes is a butchers picnic. This is when the whole idea of the game
is to destroy the other planes, the winner is the last plane left flying.
Many planes would fly (about 8) and line tangles, midair and every other
dangerous thing would be done on purpose.
