There's a story that during the testing of a fighter plane - I think the F-35 but not sure - the "developers" claimed the new computer systems made most pilot errors all but impossible.

QA engineer's first check was, what happens if I try and retract the wheels while the plane is sitting on the ground and not moving. Oops.

There are plenty of older planes with "retract wheels automatically when airborne" buttons that work by detecting a reduction in pressure on the wheels. There are also plenty of runways with slight bumps in them. The two do not work well together.
