A few days ago I posted about how a Le Mans racing team copes with a wheel falling off.
Here is a variation from the world of aviation with a surprising twist.
The landing gear on many airliners is unsafe for landing on soft grass in an emergency because it DOESN'T break

Whilst we are talking about aircraft there is a gem of an idea buried halfway down this article, along with a link to a great video of a 777 landing in a crosswind.
Test pilots don't just check what happens if something breaks - they also check what happens if something breaks and the pilot does the wrong thing in response!
You know, the way we check what happens if a dual power supply fails and the engineer takes out the wrong one to repair and then design a procedure to stop it happening for real.
