Boeing 747-8 performs the ultimate rejected take-off (RTO)

The more I fly, the more concerned I become; so many things can go wrong. The oft-stated quip comes immediately to mind when asked how your flight was, "Landings equalled takeoffs."

Precisely so. Many things can go wrong anywhere along the journey, from takeoff to flight to landing. Most problems occur, though, during landings. So I derive great comfort that engineers test for the most extreme events, such as Boeing does here.

"Full brakes are applied when the aircraft reaches 200mph. No engine thrust reversers are used. Boeing engineers and designers then watch to see if, when, and where the plane will stop."

Yes. Test. Test. And test again. I feel better already.
