AI-Generated Summary
A high-speed object was tracked on radar over the English Channel on April 29, 1957, leading to an RAF intercept attempt. The incident was officially attributed to a French test aircraft, though reports of multiple UFO sightings occurred across England on the same day.
This document consists of a Project 10073 record card and accompanying press clippings detailing a sighting on April 29, 1957. An unidentified object was tracked on radar over the English Channel, traveling at speeds exceeding 900 mph. Royal Air Force Javelin fighters were scrambled from Odiham Base near Southampton to intercept the object, but they were unsuccessful. The Air Ministry initially disclosed that the object was first sighted just before 9:00 PM. Subsequent press reports from the London Evening News and other sources speculated that the object was a new French delta-winged Mirage fighter, capable of speeds up to 1100 mph. However, some aviation sources expressed doubt that this was the correct explanation. The record card itself concludes that the object was likely a French aircraft undergoing testing. Additional notes on the document mention a series of sightings across England on the same date, including reports of 'flying golf balls' and 'cigar' shaped objects in locations such as London, Essex, and Gravesend, with some witnesses reporting TV interference and light signals.
One of the claims of the Mirage's designers, the Dassault Co., is that the plane is 'impossible to catch.'
