i heard it was about a mile
If you're referring to commercial airports, then I can't help you. The longest runway in the U.S. that I'm aware of is at Edwards Air Force Base. The Space Shuttle can land there in case of an emergency, so that runway better be really long.
No, on a long runway this is not necessary.
a Boeing 747 needs about 9,500 ft to about 11,000 ft of a runway.
the runway needs to be about 10,000 to 11,500 ft, but it also depends on the altitude, wind speed, and aircraft speed.
Runway 8R/26L is 12,000 ft long. BIG runway.
No runways 10/28 amount to 8652 meters and a380 requires The minimum length of runway for takeoff is 9,020ft and for landing, it is 5900ft.
No, not really. The only real way a airport could land any aircraft would be to have a 4 mile or longer runway. However, the problem for most aircraft is not as much landing as much as taking off, which could require a 30% longer runway.
The B-47 is a long obsolete medium bomber that was land based - they were never used on aircraft carriers, and indeed, needed more runway than an aircraft carrier could provide. Hence, the question is moot.
O'Hare's longest runway is 13,000 feet.
I Think it will last for a long time, because there are lots of designers out there. I love project runway!
The runway is 2 miles long
