History of Sailplane Directory   The original Sailplane directory was developed by Alex Holswilder in 1997 as Alex's Sailplane Directory. Alex lives in The Netherlands and recently finished his training for airline pilot at the flight academy: Nationale Luchtvaartschool at Maastricht-Aachen airport. For his soaring activities he usually goes to the Dutch National Soaring Center Terlet, flying the "family glider" Ventus 2cT "Lima Alpha". Currently there are over 390 sailplanes listed in the directory.
