There was an oversized 747 that landed at the wrong airport in Kansas City last fall. They stripped it down, flew in some short takeoff experts and got it off the ground on a runway that IIRC was 1500-2000ft shorter than the ‘minimum’ recommended runway for that particular plane.
I’ll also note that the pilot on the Malaysian flight had his own 777 flight sim setup at home. Possibly to practice short takeoff and landings.

These long runways are a safety thing.
Hi-Jackers, drug smugglers or other expert pilots would not need anywhere near the length of a standard runway for a specific aircraft.- Tom
