If Airlines Were Run Like Computer Operating Systems...
UNIX Airways
Everyone brings one piece of the plane along when they come to the
airport. They all go out on the runway and put the plane together
piece by piece, arguing non-stop about what kind of plane they are
supposed to be building.

Air DOS
Everybody pushes the airplane until it glides, then they jump on and
let the plane coast until it hits the ground again. Then they push
again, jump on again, and so on...

Air Windows
Always late, always crashes, everybody says they hate it, but it's still the
most popular airline out there.
