tail spin." one of the causes OF accidents
most commonly cited. is an acrobatic stunt which
an aviator must know how to execute with skill
and ease. In 1t he noses his machine downward
with its tail whirling In circle above him. while
its whirls in similar but smaller circle
beneath him, and he, in the pilots seat Is the
pivot of the two gyratons. To the landsman 1t
sounds heady sort Of a combination. and 1t Is
likely to prove so to the airman unless he has the
knowledge and the skill with which to manage it.
To throw his machine in and out of tail spins is
a part of his daily practice after he begins the
acrobatic training, and in very little while he
acoures sufficient knowledge of what to do and
instructive control of the machinery to execute
tail spins as easily and safely he could twirl
on his turn on his heel II his feet were on
solid ground.
But he may get into tail spin accidentally In
his early flights alone and, although he may
know what is the right thing to do to take the
machine out of 1t. he may lose his head at the
crucial moment and fail to do what he ought.
Every man, woman, or child who has learned to
ride n bicycle drive automobile is familiar
with that unconscious influence of the mind over
the muscles which causes one who has not yet
acquired complete command of machine to
drive straight at the object which he wishes and
is doing his best to avoid. The aviator has a brief
time In his training when he suffers from that
eame difficulty and nj important moments Is
proue to give the wrong pressure upon his con-
troll stick or his elevator. II he does this when
his machine goes into tail spin and his mind
does not work quickly enough to recognize his
diflculty and do the right thing. fatal accident
IL very likely to result.
