Mystery Booms

It’s a familiar story. Police and emergency services inundated with phone calls from concerned members of the public who have heard or seen something unfamiliar in the sky. Last month it was a spectacular fireball meteor.  This month it was a loud explosion that some people feared was either a giant earthquake or a bomb blast.

But the aerial bang that mystified dozens of people across a swathe of the English Midlands at 6.10 pm on 12 April was a sonic boom created by a Typhoon fighter that was scrambled in response to a false alarm.  The Ministry of Defence have confirmed the QRA aircraft was authorised to go supersonic after a civilian helicopter put out a distress call on ‘the wrong frequency’ by mistake. (Note: A detailed account of the incident has been added to the MoD website. This says an investigation is underway by the Department of Transport.)

The result was flood of calls to the police and fire services in Warwickshire, Somerset, Oxfordshire and the West Midlands. Some reported buildings shaking, windows rattling and a sound ‘like sitting on a hard shoulder and big lorry going past.’ Accounts from some of those who raised the alarm can be found on the BBC News website here.

Social media played a role in spreading rumours about the incident before the facts were confirmed by the MoD. Sky News reported that ‘theories abounded on Twitter, ranging from bomb blasts to giant earthquakes….’

Mystery booms and ‘phantom aircrashes’ are nothing new. They have become so common since the Cold War that they have become a new type of rumour legend. The BBC reported that in January this year, MoD confirmed that a loud noise heard by people in the north of England was caused by a RAF fighter jet breaking the sound barrier.

Back in March 1997 I reported on a classic incident of this kind whilst working for the Sheffield Star (see my webpage on ‘The Howden Moor incident’ here). On that occasion people in the west of the city, on the edge of the Peak District National Park, called 999 after seeing a low flying aircraft, followed by an enormous aerial explosion. Naturally they feared an aircraft had crashed into the Peakland hills. Police, fire services and mountain rescue teams scoured the Howden Moors for 18 hours and were joined by a RAF Sea King search and rescue helicopter, but found no trace of a crash. But the aerial explosions were so loud they were recorded by the British Geological Survey who confirmed they were most likely to have been caused by an aircraft breaking the sound barrier.

As today, rumours spread rapidly: were the RAF chasing UFOs over the Peak district? had a secret military aircraft crashed and been covered up? In fact, no aircraft crashed because the pilot responsible landed safely at a RAF airbase long before the police and mountain rescue teams even left their beds.

A year later I persuaded my MP Helen Jackson to ask questions in Parliament about the incident and she obtained an admission that RAF were involved in a low-flying exercise that night over the Peak. It was impossible, they said, to confirm they were responsible for the bang so long after the event, but the conclusion was obvious. I later obtained a copy of a report produced by the RAF police that confirmed my suspicions but cleverly avoided attaching blame to anyone (the cost of the pointless search and rescue operation to the taxpayer was estimated at £50,000).

Even today the story is regarded as a ‘unsolved mystery’ and frequently turns up in compendiums of UFO legends and local folklore (most recently in Jonathen Skew’s Sheffield: A Pocket Miscellany, 2011). But the truth has always been out there.

    The 12 April Typhoon deployment, the sonic booms and the intercept of a helicopter ‘sqawking’ on the wrong frequency are indeed no mystery at all. What’s been missed, however, was that prior to and during the interception (which, pace the MoD, took place near Bath, not Bristol), a cylinder-shaped ‘ufo’ was sighted ‘much higher in the sky. Some witnesses claimed this also attracted the Typhoons’ attention: inevitably, there have been suggestions that it was the true object of their attention and that the helicopter was a cover story. An image of the ‘ufo’ (probably a balloon, though I can’t confirm this) appears in the photo gallery at this link, which also includes eyewitness accounts and reader comments:
