the saucers were.

{p. 89}

"They're either interplanetary or some secret development," I said.
'What do you think?"

"The N.A.C.A. has no proof they even exist," he answered.

When I left the building a few minutes later, I was still weighing
that statement. If the Air Force or the Navy had a secret disk device,
the N.A.C.A. would almost certainly know about it. The chances were
that any disk-shaped missile or new type of circular aircraft would
first have been tested in the N.A.C.A. wind tunnels at Langley Field.
If the saucers were interplanetary, the N.A.C.A.--at least top
officials--would probably have been in on any discussion of the disks'
performance. Either way, the N.A.C.A.'s official attitude could be
expected to match the Pentagon's.

After lunch, I took a taxi to the office of the private engineer. Like
D------, he has asked that he not be quoted by name. The name I am
using, Paul Redell, will serve that purpose. Redell is a well-known
aeronautical engineer. He has worked with major aircraft companies and
served as a special consultant to government agencies and the
industries. He is also a competent pilot.

Although I had known him several years, he refused at first to talk
about the saucers. Then I realized he thought I meant to quote him. I
showed him some of the material I had roughed out, in which names were
omitted or changed as requested.
