A trip to Mexico in the best of the worst airplanes ends in a costly fiasco

Most of the airplane’s weight was on the wings as we rolled across a furrow somewhat larger than the others about halfway through our takeoff run.

The left wheel, now unlocked and slightly off-center, collapsed as the plane’s weight returned to the wheels.
