Coldwater, Michigan | During WW2 the Seabees often built runways in less than desired conditions (such as swamps, Jungles, and others). One item used in a lot of those conditions that allowed them to build the RW's was the use of interlocking steel mats, that had holes in them. This allowed for a firm base, then hauling dirt, crushed coral, and other material allowed them to build small runways, quickly for the small fighter and bomber airplanes.
The runways for the bigger aircraft were often more substantial but it took longer to get the RW in condition to support those planes. The "Bees" built whatever was needed but the top paragraph describes one way to island hop to keep moving forward. Some runways were operational within days of landing, then made more substantial as time and the situation allowed.
Now according to the AF Museum at Wright Patterson AFB though, NH3 and Oxygen were used to power the X15 airplane for about 8-10 seconds of burn, after having been dropped by a B52 bomber. That was enough to go 40 miles high and at speeds of at least Mach 6. | |
