Re: Campbell's even crazier than a MANIAC? (archeopteryx

Endurance flight can be achieved without having to sustain aerobic capacity 
for the entire duration of the flight, or for even a more than miniscule 
fraction of it.  Flap-gliding that alternates between soaring and anaerobic 
burst flapping will also suffice if the interim between anaerobic bursts is 
long enough to allow recovery.  The same technique can be used with short 
aerobic bursts  in animals that do not have sufficient aerobic capacity to 
flap full time.  This technique is suitable for flights of 500-1000 
kilometers/day.
