Howden Moor sonic booms and 'crash'
At about 22:00 on 24 March 1997 two loud booms were heard and recorded over the Dark Peak; people reported a low aircraft and a glow on Howden Moor, setting off a night-long search.

The account
Police, the RAF and about 150 mountain rescue volunteers with dogs searched the moors; nothing was found. A triangular UFO had been reported locally an hour earlier. The RAF denied any supersonic flights.
The sceptical view
Suggested explanations include a military jet breaking the sound barrier, which would explain the booms but not the 'crash' reports.
The researched reading
Real, instrument-recorded booms and a night-long search that found nothing. An unacknowledged supersonic aircraft or space debris is likeliest, and the “crash” was probably separate events linked together.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 38% | Low-flying aircraft were booked over the Peak District earlier that evening. Glows on the moor are often flares, lamping or fires, and witnesses linked separate sights and sounds into one “crash”. |
| Secret human technology | 23% | Seismic stations recorded two sonic events at 21:52 and 22:06. The MoD denied RAF and NATO supersonic flights, which leaves an unacknowledged military aircraft, perhaps a foreign one, as a real possibility. |
| A known natural phenomenon | 12% | A bolide or re-entering space debris can make sonic booms. An RAF report reportedly suggested a satellite re-entry, but two booms 14 minutes apart fit poorly with a single bolide. |
| Perception, memory or mind | 12% | After an earlier triangle report, residents primed by the booms reported low aircraft and glows that may be unrelated. |
| Genuinely anomalous | 8% | Recorded booms, multiple witnesses and a large search that found nothing give a real, if small, residue. |
| A poorly understood natural phenomenon | 4% | Some skyquakes remain unexplained. |
| A hoax or fabrication | 3% | The booms are instrumentally recorded. |
Official position: The MoD said no RAF or NATO aircraft caused sonic events; police said no explanation was found.
