Project 5,6 ~ IN-FLIGHT FARTICIFPATION OF AN F-101A
AlnCesFT ~ Captain M, H. Lewin

OBIRCTIVE
The objective of Project 5,6 is to determine the responses of an In-flight

F.-101A aircraft to the thermal, blast, and cust effects of a nuclear detcaztion.
A correlation of the responses, combined with known characteristics of «r
weapon, will be used to define the raxirum safe delivery capability of the air
craft.

STRULENTATION
The aircreft was instrimented with radicneters, calorir.:ters and : oe

transducers to measure the thermal and blast inputs and with strein gases,
thermocouples and various other instruréents to neasure the aircraft 1c cptntes to
