It was planne? to position the B57 in a position corresponding to approx— imately 80 ~ 25 pereent limit lea2 on the critical member of the ATPaRAwr peartrtaY q™ gmanD The JBeS7B was flying at an absolute altitude of 17,255 feet, headirg 073° in a tail~on position at H # OC. Forirontal range to greund zero at H # O was 34,000 feet (aircraft traveling at 2.2 ft/sec). Air- craft position at time of shock arrival (H /# 79 seconds) has not been received from Raydist, Needing and altitude same at H # OQ. RESTITS DELET<0 - 69 -
