Guy westgates display was done at dusk, so not "night" under the legal definition. Lasham did some proper night flying last december in a Bocian. It is the only glider as far as we know that is approved for night flying and is fitted with nav lights.. The runway was lit with £250 worth of lights and batteries from Poundland.
Lasham members Gordon MacDonald, Colin Watt & Patrick Naegeli all took to the skies in their specially prepared Bocian E glider.
