429 aa -. 430 (exIE) Project 5.4 - In-Flight Participation of a B-57E let It Harold M, Wells, Jr. QRECTIVE The objective of thie test was to measure the effects of a low yield nuclear detonation of an in-flight B-5S7B aircraft weapons system. INSTRUMENTATION Out of 220 channels being recoriei, 10 data channels vere lost for various reasons, ’ They have been repaired, or replaced by spares. AIRCRATT POET ion Dt sPacr The JB-S57B was flying at ean absolute altitude of 10,140 feet, heeding 052° T in a tadl-on position et t,- Horizontal range to ground wero et t, vas 3629 feet (aircraft travelling at 710 ft/sec). Aircraft position at time of shoce arrival (4 4 12.56 seconds) has been determined to be 14,006 feet beyond ground sero. Heating seme as ty al- titude 10,540 feet.
