May 21, 2012 CHANNEL ISLANDS An investigation has been launched into the cause of a mysterious boom which shook buildings across the Island on Saturday afternoon. Hundreds of Islanders reported hearing a loud bang similar to a sonic boom at 1.04 pm. The boom was so loud it rattled doors and windows from Gorey to St Ouen and even measured on the Island¹s seismograph in St Aubin. But despite speculation that the noise was caused by a military jet travelling faster than the speed of sound, Jersey Airport has confirmed that no aircraft capable of causing such a noise was in the Island¹s airspace at the time. And Jersey Met Office has confirmed that it is unlikely that any meteorological phenomenon could have caused the noise. -TIJ
