Aviator Who's Established Altitude
Mark Will Attempt to Beat Record

DAYTON, ohio. --- Lieut.. John
a. Macrcady McCook field aviator,
who established the worlds altitude
record OF 40 500 feet last September.

arations for anothr history making

high an IL was possible for him to
go. with tho lie poro plane equipped
az it then was. In other words, he
reached an altitude whore the at
mOsphCrlc pressure was only three
pounds To the square inch, and the
superCharger refused to function
properly In that rarctied stratum OF
air.
A superchargcr Of greater ca
pRcity and efficiency has been con-
structed, and upon It's efficiency he
believes II will he possible to reach

altitude no hopes 20 reach In snfety

that tremendous altitude.
a number OF things may happen,
For ono thing the supercharger may
not work, tho engine may fail, the
plane may crumple, and the pilots
body may explode.
BODY May Blow Up.
Macroady Is going TO make the at
