explanation for this discrepancy to date.

There has been no

The arrival of the shock-

wave at 159.1 seconds after burst and the accompanying overpressure
of 0.237 psi, agreed very closely with the predictions.

The recorded

maximum skin temperature rises ranged from zero to forty-two percent

lower than predicted for the total thermal energy recorded.

The fuse-

lage pressure gauges sensed the unsymmetrical loading received from
the shock wave by registering higher overpressures on the side of the
shock wave arrival.

The effects B-47 received no appreciable damage.

A very small patch of paint on the right elevator trim tabs was blis-

tered and the gelatin filters on the GSAP cameras were burned.
On ROMEO, the effects B~-36 was one second early and a little to
the left.

Raydist malfunctioned on this aircraft and no results were

obtained.

The B-36 received damages similar, but less extensive, to

those on BRAVO.

Repair was estimated at 100 man-hours.

Flight crew

reactions and observations during ROMEO were the same as on BRAVO,

with the exception that two distinct light pulses were seen through
the asbestos window shields.

It is.possible that there were two light

pulses on BRAVO, since it is characteristic of this type detonation.

The jet tailpipe temperatures reached the gauge limit (1000° C) and
probably exceeded the figure.

No notable thermal damage was observed,

however.
There were several minor aborts, all considered primarily due to
the length of time the aircraft had sat on the ground in preparation
