The heading was 120 degrees trus, in a tail—on aspect to Ground Zero. Raydist figures were not available at this writing. Incident thermal energy wa megatons. Using these figureB and the weapon's yield was 1.6 as a basis of comparison, the thermal rises in 0.020 aluminum skin were twenty-five percent higher than pre- dicted. The temperature rises ranged from a 21° F peak value in 0.188 to 205° F in 0.020 aluminum skin. At shock time, the horizontal range of the aircraft was 81,000 feet and the measured peak overpressure was 0.25 pai plus ten percent at all stations. aircraft in 74.5 seconds.
