What if a plane gets tangled up in it?
- hwillis 10y agoProposals were made around 1000 km altitude at the lower tip. Boeing proposed a 600km tether with a transfer altitude of 100km (at mach 10), and later increased that to 150 km. The Lockheed U-2 is one of the highest flying airplanes ever, our main cold war spy plane. It flew twice as high as a passenger jet, and cruised at 70,000 feet, just over 21 km. Planes would not get tangled in it.
