 Case #21

Heathrow, London, UK - December 17, 1992

All we have on this British case is a scrap of info from the MoD files summarizing a report made by two air traffic controllers at London's Heathrow Airport. We reproduce this document below with thanks to Dr. David CLARKE for bringing it to our attention.

MoD file summarizing a report made by air traffic controllers

Comment - At 08:20 ZT on December 17, 1992, the Sun was just clearing the horizon at 132°. The UAP was estimated to be at a distance of 7 miles (11 km) and disappeared "steadily". It is not sure what the "130" means at Q.6. Perhaps this is the terminal azimuth, which would imply a 40° motion.

How to picture an "inverted boomerang shape" is also open to interpretation. In essence, all we have are a few lines mentioning a black silhouette observed against a dawn sky.

The authors look forward to receiving additional reports and/or comments which may help assess the soundness of the mirage theory for this particular type of UAP sightings (to contact us, see our e-mail address on the contact page).
