"Daring young men in their flying
machines ..." the old tune rings true
today when describing acrobatic pilots.
Spinning, looping, rolling acro
batic planes look like gulls wheeling
their way across the sky.
Pilots insist anyone can learn to per
form acrobatic maneuvers - vv, n;
Tve taken people up who have
never flown before and had them per
forming simple rolb end loops," said
Marvin Helman, a part-time aerobatic
flight instructor. "But that only hap
pens after careful ground instruction
first." . ,.- .. ' : : .

Helman said people who "do a lot of
roller coasters, and trampolines" have
an easier time getting acclimated to
some of the sensations. But unlike a
roller coaster, the ride is smooth and
quiet . v
Despite the smoothness, there are
'physical stressors. ij-.-jv;!i .ii'
"Pulling anywhere from three to five
G's is stressful on the body " said Hod
Oliverius, Helman's former student. "Af;
ter 10 minutes of maneuvers, you're
fine. After 20, you're tired. After 40,
you can get pretty sick."
Acrobatic pilots do normal maneuv
ers and inverted maneuvers. Normal
maneuvers, performed rihtside-up,
cause you to be'puiisd into your seat
with a certain force; thb phenomena is . .
known as "pulling pecltiva G's." This
means that if you weih ICO pounds
' and a maneuver causes you to pull two :
G's, you are pulled fcto your seat as if
" you weighed 200 pounds.' ; ' V . ,
Inverted maneuvers, performed
upside-down, puHyou a'ayfrcm your
