Decades ago I landed a Twin Otter at Harare, Zimbabwe. The terminal was at the far end of the runway. My capatin just turned to me and said: "land long". I replied: "yeah, I figured that out." That runway is 15,500 feet long (14,500 or so more than a Twin Otter needs to land and stop).
Apparently this runway was built so long to accomodate BOAC Comet's hot and high performance requirements in the day.
