Gap seals

[Rob Neils <RobNeils@aimcomm.com>]

At high altitudes how quickly the L/D deteriorates with airspeed becomes 
very important.  Very high altitudes require speed to keep from stalling 
since the range between cruise and stall becomes less - it's "coffin 
corner."  "Floater" gliders don't work well in a wave.  They drag down too 
quickly with increased speed.  A very good L/D at cruise (efficiency) makes 
for a great wave machine.

The Europa ought to be a very fine machine at very high altitudes!  :)
