Of course, all plane runways are long enough for airplanes to land. But there are situations, when jets overshot a runway. Such case happened in Jamaica last winter. There were over 150 passengers aboard an American Airlines flight going from Miami to Jamaica. The weather was not nice, as there was a heavy rainstorm. The jet overshot a runway when it was landing, and broke up in 3 parts. Good, no one was fatally injured.
