Don't believe in flying saucers? Neither do we, but that doesn't necessarily mean that there can be no other way for Earth to get its last....

WARNING
FROM THE STARS

ILLUSTRATOR SUMMERS

IT WAS a beautifully machined container, shaped like a two pound chocolate candy box, the color and texture of lead. The cover fitted so accurately that it was difficult to see where it met the lip on the base.

Yet when Forster lifted the container from the desk in the security guards' office, he almost hit himself in the face with it, so light was it.

He read the words clumsily etched by hand into the top surface with some sharp instrument:

TO BE OPENED ONLY BY:
Dr. Richard Forster,
Assistant Director,
Air Force Special Research Center,
Petersport, Md.
CAUTION: Open not later than
24 hours after receipt.
DO NOT OPEN in atmosphere less
than equivalent of 65,000 feet
above M.S.L.

He turned the container over and over. It bore no other markings—no express label or stamps, no file or reference number, no return address.

It was superbly machined, he saw.
