MS-DOS Airline

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.

MS-DOS with QEMM Airline

The same but with more legroom to push.

MacIntosh Airline

All the stewards, stewardesses, captains, baggage handlers, and ticket
agents look the same, act the same, and talk the same. Every time you
ask questions about details, you are told you don't need to know, don't
want to know, and that everything will be done for you, so just shut up.

OS/2 Airline

To board the plane, you have your ticket stamped ten different times by
standing in ten different lines. Then you fill out a form showing where
you want to sit and whether the plane should look and feel like an ocean
liner, a passenger train or a bus. If you succeed in getting on the
plane and the plane succeeds in taking off the ground, you have a
wonderful trip...except for the time when the rudder and flaps get
frozen in position, in which case you will just have time to say your
prayers and get in crash position.

Windows Airline

The airport terminal is nice and colorful, with friendly stewards and
stewardesses, easy access to the plane, and a completely uneventful
takeoff...then, once in the air the plane blows up without any warning
whatsoever.

Windows NT Airline

Everyone marches out onto the runway, says the password in unison, and
forms the outline of a plane. Then they all sit down and make a
whooshing sound like they are flying.

Unix Airline

Everyone brings a piece of the plane with them when they come to the
airport. They all go out on the runway and put the plane together piece
by piece, arguing constantly about what kind of plane they are building.

Newton Airline

After buying your ticket 18 months in advance, you finally get to boardthe
plane. Upon boarding the plane you are asked your name. After 46
times, the crew member recognizes your name and then you are allowed to
take your seat. As you are getting ready to take your seat, the steward
announces that you have to repeat the boarding process because they are
out of room and need to recount to make sure they can take more
passengers.
