737

[c9]

The Boeing 737 is the most popular airliner of all time. Boeing has actually sold more 737s than Airbus has sold airplanes. If you've been in the air, you've probably been on a 737 (unless you've only flown to Fredericton). On the average about 1,250 737s are in the air at all times; one takes off every 5 seconds.

Finally, some catty marketing from Boeing:
