Bbc report of nasa contacts w/alien species

I recently heard a Radio One program in the UK that contained
an interview with a leading proponent of the popular "US Government has
aliens locked up and is experimenting with their spaceplanes" conspiracy
theory. However this particular individual sounded very reasonable, did
not make any outrageous claims, and further had some interesting facts
to disclose. In particular he mentioned several verifiable facts which
I would like some followup on:
Rockwell International and NASA were planning a *massive*
joint exhibition of space exploration this year (1991) but it was delayed
inexplicably until 1992. In the *official* prospectus for this exhibition,
one of the exhibits was clearly stated to be "an extraterrestrial space
craft". When asked about this by various individuals, all enquiries
were referred by NASA to the US DoD. An unnamed Pentagon spokesman speaking
off the record is meant to have indicated that they "had a number of such
vehicles to choose from..."
The Pentagon also held a press conference to deal with press
inquiries on this matter - and refused to answer any questions. In fact
reporters later said that the Pentagon had asked most of the questions,
and they all pertained to "what would be the public reaction if...".
The guy on the radio program referred extensively to two NASA
consultant engineers who claimed to have worked on alien spacecraft
studying propulsion systems for NASA - both had high level security
clearance in the States, were verifiably employed by NASA as senior
consultant engineers, and both were phoned in the States by the station
in a followup program (which I missed) the next day. The followup program
incidentally was only scheduled at the last minute due to record phone
calls from the public swamping Radio 1's 64 line switchboard...
He also claimed that a NSA official had told him off the record
that the NSA was in "electronic communication" with at least eight
extraterrestrial sources of intelligent communication...
He claimed that he possessed a recording of a telephone conversation
with an ex deputy director of the CIA (Casey's deputy as I recall), who
said that they (the CIA) had possession of quite a few alien artefacts,
including bodies, spacecraft and other miscellaneous bits and pieces.
He also verified on tape claims that several alien landings at US AFBs had
occured in the past, and in some cases were common knowledge amongst certain
groups of AFB personnel: "Hear what came in this morning, Joe?"...
Various farmers in a certain area of the US (I forget the state
that was mentioned) regularly discovered bloodless (drained) cattle in
various stages of dismemberment in the early morning. These animals had
had certain glands, body parts, or body fluids surgically removed with a
precision beyond the capabilities of all but the most advanced surgical
laboratories. This problem was so bad that in one place a farmer was in
danger of going bust due to loss of cattle. One explanation advanced was that
aliens were using these cattle as a convenient source of various rare
chemicals/tissues.
The technology in the latest black projects that have progressed
to flight hardware - Aurora, Strike, etc. - seems to be well beyond the
capabilities of current commercial (defense/aerospace) technology. In
particular ablative control surfaces and reliable flight control at speeds
in excess of Mach 4 are characteristics of such craft, sightings of which
are widespread in Nevada along with reliable evidence (supersonic boom
disruption?) of such speeds.
Any comments/hard info. on any of these assertions would be
much appreciated - please post as I am sure others are interested too.
