1. The distance and. Ughtius conditions wider which the
source sighted the tmusual object vault sake it extsvnely difficult
to determine just what vas beins ceon. in some degree, the
description fits a vertiail tape-oft aircraft or a scissile or
aircraft launched from a zero length rail. The-zero. length launching
could most certainly be accas;glished only with a rocket mblah would.
produce a lwPs'flame,and,smoke which would have been very noticeable.
The spiraling of the object as it left the launcher does not fit very
veil with a vertical, take-off aircraft.
2. The very anal]. amount of details given in the referenced
report does not permit an identification of the object sighted. It
does,.houever, teed.to iiidicate?that it.vas not a "flying saucer".
In 19%, the Scientific Advisory Board to the Chief of Staff,.1 AF,
appointed an ad hoc committee of three scientists to evaluate
project "Y".' The committee found that several factors had been
overlooked orrsinimised in their d relc Gent, such as payload,
drag factors, and mechanical design problems, to such an extent that
the cormittae recoaaaeVAed s net support for the project. Air Three
support of the project now is in basin research concerned with
vertical thrust which codifies conaidurably the flying saucer concept.
