Sky birds dare!

"Ace glider pilot Breeze Callahan is trying to demonstrate to the Navy the value of gliders and gliding techniques in war. There are two ways Breeze believes they can be used to aid the war effort: they'll keep a plane aloft when engines cut out, and gliders will be able to enter enemy airspace silently--a perfect way to spy undetected. Callahan's ruthless competitor, Badger O'Dowell, has other ideas. Badger is determined to get the Navy to buy his training ships instead. When testing gets underway to prove the strength of their designs, sabotage and betrayal threaten to destroy not only Callahan's dreams of glider flight in war, but also his life"--P. of cover flap.
