Results of "Actual Flying Conditions" Test on WASP Intermediate Flying Clothes.

Clothes Tested:
Subject 1: Alpaca lined intermediate flying suit, A-6 boots, one AAF A-11 glove, one Experimental three fingered insulated glove, intermediate helmet, "green" trousers and shirt, sweater, thin underwear, medium wool socks, shoes.
Subject 2: Alpaca lined intermediate flying suit (J. Cochran sample), gloves as above, "pink" trousers and shirt, medium wool socks, thin underwear.

Flying conditions:
Two hours at temperature between 5°C and 0°C.
Single engined plane (AT-6).
Wind from half-open hatch (slightly more than normal), direct on Subject 2 in front cockpit and indirect on Subject 1 in rear cockpit.
Normal "flying" activity for subject 2; slight activity for Subject 1.

General Results:
Warmth: Both subjects reached the "chilled" point after 2 hours at test temperatures, but were not uncomfortable and felt the clothing adequate for this temperature, wind and duration.

Comfort: Both subjects found clothing in general practical and suitable for the job.

Specific Results:
(Helmet, gloves and boots written up on separate reports - not WASP equipment. However warmth was sufficient).
Subject 1:
Warmth: Generally clothing sufficient.
Unnecessary separation between trouser cuffs and boots.
Collar sufficient without muffler.
No separation between trousers and jacket.
Comfort: Sufficient movement.
Cuffs tend to separate from boots.
Horizontal square pockets awkward to use.
Leg pockets good - essential.
Knit wristlets good.
This men's clothing absolutely inadequate for use of relief equipment.

Subject 2:
Warmth: Even with direct wind from open hatch alpaca good protection for cold at this temperature and duration. Front of jacket especially warm. Back and shoulders chilly first - probably from wind.
