The sailplane is attached to one end of 800 to 1,200 metres (2,600 to 3,900 ft) of cable and the winch rapidly winds it in. The sailplane can gain about 270 to 910 metres (900 to 3,000 ft) of height with a winch launch, depending on the headwind.
A sailplane at 90,000 feet altitude flies in approximately the same aerodynamic regime—Mach and Reynolds numbers—to be experienced by a moderate size aircraft flying near the surface of Mars. A sailplane may carry aerodynamic instrumentation to measure the boundary layer behavior in this regime better than can be done in any wind tunnel.
