[Thirstquencher] how does an airfoil work
[WinslowLeach] what is this? Trivial Pursuit?
[Thirstquencher] none of you knows how an airfoil works?
[CasperVanDien] a device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight
[RangerOfTheEast] airfoil keeps food fresh
[Thirstquencher] but how come an airplane can fly inverted?
[Thirstquencher] it still generates lift upside down
[bluecifer] just because we don't answer doesn't mean we don't know...usually it just means we don't care
[Thirstquencher] and you are gay
