Larry,

Although there are a few candidates, I would have taken any
reference to a 'pumpkin seed' experimental aircraft as relating
to the hypothetical black aircraft which would use an 'exotic
propulsion system'. As mentioned on the Federation of American
Scientists' web site:

While the depiction of an Aurora aircraft seems consistent with
the confines of present technological imagination, other SR-71
follow-on prognosticators suggest more alien craft. Aviation
Week & Space Technology has proposed a current black aircraft
that is something akin to a 1960s Sci-Fi concept. They depict an
elongated diamond shaped vehicle (one hesitates to call it an
aircraft) similar to a "flattened football." The airframe's
dimensions might be 110 x 69 feet. Due to intense heat, the
vehicle would have a heat-streaked appearance similar to that of
the space shuttle. Contrary to intuition, the aft body would
appear distinctly more pockmarked than the fore sections, as if
the most intense heat was experienced in this region.

This vehicle would have a dual propulsion system. Jet engines
buried in the fuselage would propel the vehicle to supersonic
speeds, when a novel external burning mechanism would take
control as the fundamental propulsion method:

"In the high Mach regime, misted fuel is ejected from the
fuselage midsection -- the 'break point' of the elongated
diamond -- across the aft surface tiles, into the area between
the fuselage and a shock wave attacked to this break. In
essence, the sloping, converging aft fuselage sections form the
inside of a 'nozzle' and the shock boundary constitutes the
outer surface, creating an expanding exhaust effect, much like
that on a conventional rocket. The fuel is ignited by surface
heating -- or other means -- creating combustion that
accelerates the aircraft up to the Mach 6-8 regime."

Eliminating the human life-support requirements at Mach 8, this
flaming, hypersonic pumpkin seed would be unmanned and capable
of on-board self- control. This vehicle would be as destructive
as it is unusual. A payload of 120- odd nuclear weapons would be
dispensed as the flaming stone skipped across enemy skies. [End]
