ihe DELETED Project 5.4 = In-Flight Participation of a Be57B = It Harold M. Wells, Jr. Objective The objective of this test was to measure the effects of a nuclear detonation on an in-flight B~57B aircraft weapons system. Instrumentation Out of 240 channels being recorded, 14 data channels were lost for various reasons. They have been repaired or replaced by spares. Aircraft Position in Space The JB-57B was flying at an absolute altitude of 16,050 feet, on a 120° T heading in a less than 2° nose left position at H # 0. Horizontal range to ground zero at H # O was 16,960 feet (aircraft traveling at 736 ft/ sec). Aircraft position at time of shock arrival (H # 34.9 sec) was 43,630 feet beyond ground zero. Heading same as H f 0, altitude 18,050 feet, speed 730 ft/sec.
