Cosford 1993: a re-entering rocket, and a Shawbury sighting 90 minutes later

In the early hours of 31 March 1993, police and military witnesses across Britain, including an RAF police patrol at Cosford, reported bright lights in the sky. An MoD desk officer argued an unidentified object had evaded UK air defences; The National Archives later concluded most sightings were a Russian rocket re-entering the atmosphere.

Thirty reports in one night

The Ministry of Defence file DEFE 24/2086, released at The National Archives, covers UFO reports from the night of 30–31 March 1993 ^[1]. The Archives' guide to the release says it deals with bright lights seen across central England in the early hours by police officers and military witnesses, including a police patrol at RAF Cosford, near Wolverhampton ^[2].

The list kept by Sec(AS)2a, the MoD branch that handled UFO reports, runs from a sighting at 21:00 on 30 March in the Quantock Hills, Somerset, to one at 02:40 on 31 March at RAF Shawbury. Most reports cluster between 01:09 and 01:20, from Devon, Cornwall, Somerset, Staffordshire and Pembrokeshire ^[5]. British Summer Time had begun only on 28 March, and some signals mixed local time with GMT ^[5].

The case takes its name from a two-man RAF police patrol at Cosford, which reported at 01:15 two bright lights about 1,000 feet above the ground, moving fast towards the south-east ^[5]. According to David Clarke, the patrol rang ahead to warn the Meteorological Office observer at RAF Shawbury, about 20 miles away, that the object was coming his way ^[6].

The file includes more than 30 sightings during a six-hour period.

What the Shawbury observer reported

The desk officer's handwritten note on the Shawbury sighting, with the witness's name blacked out, gives the time as 2.40 am local. The object was stationary, then moved straight up and zig-zagged; it showed two red lights and a narrow white beam, like a laser, that seemed to be searching the ground. At its lowest it was put at about 400–500 feet, 1 or 2 km from the base; it then passed directly overhead at about 4,000 feet heading almost due south, now showing three red lights ^[4].

Clarke identifies the observer as Wayne Elliott. Elliott's own Met log, kept in GMT, records the Cosford warning at 0030Z and his observation at 0140Z, which places his sighting at 02:40 BST, about an hour and a half after the Cosford report ^[6].

In a 1996 interview for the Met Office magazine Mercury, Elliott described the beam sweeping the countryside and a low humming noise as the lights crossed the airfield; he said he did not recognise the object as either a fast jet or a helicopter ^[6].

Guesstimate of objects size: somewhere between C-130 and 747.

Nick Pope's case to his superiors

On 6 April 1993 Sec(AS)2a asked London Air Traffic Control Centre (Military) to copy the radar data to video tape for examination ^[4]. On 16 April the desk officer, Nick Pope, wrote to the head of his department that nothing had been detected on air defence radar at RAF Neatishead or on air traffic control radar, argued that the reports did not fit a satellite re-entry, included the Shawbury report and raised the speculated US aircraft Aurora ^[4]. His line manager added: "It would certainly appear that some unidentified object was seen." ^[4]

The Assistant Chief of the Air Staff, Air Marshal Sir Anthony Bagnall, was then briefed that there was evidence a UFO had evaded UK defences ^[2]. Clarke dates that briefing to 22 April and quotes it as saying the sightings "match some of the reported characteristics of the so-called Aurora"; inquiries by the British air attaché at the Pentagon drew a blank ^[6].

It seems that an unidentified object of unknown origin was operating in the UK Air Defence Region without being detected on radar

The radar replay and the rocket

The radar replay, sent to Sec(AS)2a on 19 April, listed an aircraft transponding overhead Shawbury at 0146Z, heading south at about 20,300 feet, during the time of the Met observer's sighting. The released file shows no sign that this entry was followed up ^[4].

On 7 May Pope told DI55 that radar returns over Devon and Cornwall between 01:10 and 01:20 were probably clutter, and that the UFO group BUFORA had pointed to the re-entry of a Russian rocket booster, catalogue number 22586. RAF Fylingdales gave him a re-entry time of 02:20 local ^[4], with an error margin of an hour either way ^[6]. Pope accepted that the decay might explain some high-level sightings, but not the low-level ones, the report of a low hum or the Shawbury Met officer. The head of Sec(AS) wrote on the minute: "I suggest you now drop this subject." ^[4]

Object 22586 was the second stage of the Tsiklon-2 rocket that put Kosmos 2238 into orbit on 30 March 1993. McDowell's catalogue lists it re-entering that same night, at about 23:45 UTC on 30 March, with the time marked uncertain ^[7]; Clarke, citing US Space Command and NASA data, gives 1.15 am BST ^[6]. The National Archives' 2009 release concluded that the majority of sightings were caused by this rocket re-entering the atmosphere ^[2][3]. In March 1994 Pope himself wrote to the Spanish researcher Vicente-Juan Ballester Olmos that most of the night's sightings could be attributed to it ^[6].

Shawbury revisited, and what the files show

In 2005 an airman who had served at Shawbury told the Daily Mail the lights were a Dyfed-Powys police helicopter using its searchlight to follow a stolen car. Elliott told Clarke the same year that the hum and the beam were very similar to what he would expect of a police helicopter; flight logs no longer existed, so the identification cannot be confirmed ^[6].

Popular accounts describe a single huge triangular craft passing over Cosford and then Shawbury in quick succession; the MoD papers instead record two bright lights at Cosford at 01:15 and, about 90 minutes later, red lights and a beam at Shawbury, and Pope's original notes describe no triangle ^[5][6].

DEFE 24/2086 was part of the fourth instalment of MoD UFO files released in August 2009 ^[3]. A parallel DI55 file, DEFE 23/254, opened in 2019, contains no evidence of further investigation after the Assistant Chief of the Air Staff became involved ^[6].
