  In their successful invasion of Crete, the German army
demonstrated to the world a new technique in modern
military invasion. Scores of large troop carrying gliders
brought men and materials to the island which was soon
it? the hands of the invaders. This was not the first time,
however, that the Germans had benefited from the use
of gliders. The formidable Luftwaffe had been made
possible by the large number of German youths who had
been taught the fundamentals of flying in small sport
gliders.
  The United States has by no means been asleep in the
development of a glider force for its army. Several
months before the attack on Pearl Harbor, Lt. Gen. H.
H. Arnold, commander of the U. S. Army Air Forces,
announced that we would build a glider force second to
none. We are now well under way in the mass produc-
tion of these motorless craft for our armed forces.
  The leading manufacturer of gliders in the United
States is the Laister-Kauffmann Aircraft corporation. It
began a year and a halt ago when Murray Whitehead
and John R. Kauffman, who were trying to speed up the
development of a light plane designed by Whitehead, met
Jack Laister, who had been building gliders since he was
fifteen and now had an invitation from the Army Air
Corps to submit a design for a two place training glider.
The company, which resulted from their meeting, has al-
ready outgrown one plant and has taken over a large
arena which had formerly held flower exhibits, dog shows
and such.
  Some of the parts of the small craft are sub-contracted,
but the main parts, the wings and fuselage, are made in
the plant. The fuselage frames are made from lengths of
steel tubing which is fashioned into small sub-assemblies,
which are welded into larger assemblies until the fuselage
is finally done. The wings and tail surfaces are made
mainly of three-ply spruce plywood, which is shaped into
hundreds of rigid parts that make up the wing and tail
assemblies.
  The hundreds of parts that make up the Laister-Kauff-
man glider are made as carefully as those of the finest
pursuit plane. The glider is fabric covered except for the
leading edge of the wing which is covered with plywood.
The main parts of the glider are assembled one by one
until the control cables; wing, elevator and rudder "tabs",
small control surfaces used to trim the ship in flight; wing
and tail running lights; radio; control instruments; seats;
landing wheel (just one) and plastic cockpit hood are
finally in place. The completed glider weighs just 450
pounds of which only 150 pounds is steel tubing.
                       Testing
  The small ships are given a rigorous test by the chief
pilot. It is towed to an altitude of 4000 feet by a tow
plane, and the glider pilot then cuts loose. Test maneu-
vers include spins, stalls, dives, sharp banks and side
slips. When the glider is picked up by the tow plane,
an ingenius tow reel takes up the shock.
  When the glider has passed its final inspection, it is
loaded onto its custom built trailer ready for delivery.
The wing halves and horizontal tail surfaces are remov-
able so that the glider takes very little space when trans-
ported or stored. A trained crew is capable of removing
the glider from the trailer, assembling the wings, fuselage
