Have Blue and the F-117: a secret that held for a decade

A faceted black aircraft that looked like nothing that should fly, developed from a Soviet physics paper, tested over Nevada from 1977 and denied until 1988.

A dark angular military aircraft

The faceted shape follows from what a 1970s mainframe could calculate, not from any exotic requirement.

Documented. Have Blue was the demonstrator; the F-117 Nighthawk was the production aircraft. First flights were in 1977 and 1981 respectively, and the aircraft’s existence was not acknowledged until November 1988.

Where the idea came from

A paper. In 1964 a Soviet physicist, Pyotr Ufimtsev, published work on how electromagnetic waves scatter from edges. It was theoretical, unclassified, and the Soviet authorities saw no military application.

Illustration

A Lockheed engineer found it, and realised the equations allowed radar reflection from a shape to be calculated — which meant a shape could be designed to reflect radar away from its source rather than back.

The faceted appearance follows directly. The computers of the 1970s could only solve the equations for flat surfaces, so the aircraft was built from flat panels. Later stealth aircraft are curved because later computers could handle curves.

What it was like to see

Black, angular, and flying at night over Nevada for a decade before anyone would confirm it. It handled poorly enough that pilots called it the Wobblin’ Goblin, and it needed continuous computer intervention to stay in the air.

Sightings occurred and were denied. When the aircraft was finally acknowledged in 1988, the released photograph was deliberately poor.

The lesson for UFO reports

This is the strongest available case that unfamiliar aircraft account for a meaningful share of unexplained sightings.

An observer in Nevada in 1980 seeing a silent black angular object at night would have been reporting something real, unidentified and genuinely secret. They would have been told it did not exist. They would have been right, and the denial would have been official policy.

The timeline that matters

Eleven years from first flight to acknowledgement, and about twenty-five from concept to full public documentation.

That is the realistic secrecy horizon for a major American aircraft programme — long enough to be significant, short enough to be measurable. It is the number to hold against any claim that something has been hidden for half a century with no trace at all.

Still open on this one:

    How many F-117 sightings entered the UFO record before 1988?

    Reports from Nevada and later from operational areas would have been unexplainable at the time. Nobody appears to have gone back and matched them against the now-public flight history.
