'Crazy wartime mission' ??? haven't you heard of the glider troops that wer= e an essential part of d-day, capturing Pegasus Bridge and others putting o= ut of action some of the batteries of big guns that overlooked the landing = zones, before the ships arrived? I have never heard of more than one glider per tug plane, the likelihood of= gliders hitting each other would be too great, remember that practically e= very glider based mission by the allies was carried out at night. I could e= nvisage the three wires being used for ground, supply and bidirectional aud= io between the tug and glider, as they would save as much weight as possibl= e in the glider to maximise the amount of payload carried, so having a batt= ery to power comms with the pilot would be something to do away with. It wo= uld need to be a large (probably car battery size) to last long enough for = the trip across the channel and that would be quite a weight penalty, and i= n the event of a crash landing it would become a fire hazard as the gliders= were all wooden construction. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
