the former altitude record of $3.50

Schroeder was quick to congratulate
Lieutenant Macready on having won
the high flight crown OF lclcies."
MaCrcady Lauds Comrades"
Spinning down In great splrals
from out of tho heavens at the end
of his erve-numbing exploit,
Lieutenant Macrcady calmly re-
marked that he hadn't intended to
break any records when he left the
ground.
Il went up primarily to test a new
propeller and additional equipment
on the supercharger," he said "Afy
record flight was test flight and
the record was incidental to the
very valuable engineering. popeller
and supercharger data which was
obtained"
Then he spoke in high terms of
both supercharger and propeller,
He praised their performance. the
smoothness OF their work. saying
nothing, however. about his own
courage and endurance. They were
his comrades" these things OF cold
metal, and he generously gave them
the biggest share OF the credit.
Particularly did he mention the
efficiency OF the supercharger. that
extraordinary apparatus designed by
Or. Sanford A. Moss OF the General
Electric Company's Thompson lab
oratory at Lynn, Mass.
Lieutenant Macready declared
that mans own physical weakness,
rather than any mechanical limita-
ton OF man-inade mechanism Is now
the big problem OF high flying.
"Superchsrgers," he said. ARE
now In such n high state of deYel-
opment that they should be fairly
consistent at extremely high alti-
tudes In the future. Yet, In my opin-
ton altitude records will not be
gagged by the superchargers them
selves, but by the physical limita-
lions of the pilots. To get much
higher, greater provision for the
men will have to be made, somehow
or other or ii will be impossible

The superCharger does the same
thing for the engine that the oxygen
masks do for the pilot--prevents
