Were mysterious bangs heard all over Britain and in New York caused by U.S. stealth jet? Expert claims noises mimicked 'pulse detonation engine' - which could power rumoured Aurora project

•Sounds reported last night from Aberdeen to West Sussex to Devon

•Twitter users blamed meteors, fireworks, aliens and 'the end of the world'

•A woman in south London managed to record the mysterious bangs

•Now an expert says the noises sound like a 'pulse detonation engine'

•Dr Bhupendra Khandelwal is helping develop technology behind engines

•Conspiracy theorists say power source could be behind U.S. spy plane

•MoD said no aircraft scrambled; Met Office said unusual weather not cause

An expert claims the loud bangs which baffled Britons last night sounded like a type of experimental jet engine - which conspiracy theorists enjoy linking to a rumoured spy plane.

Dr Bhupendra Khandelwal added his comparison to a debate which began when hundreds of Twitter users from Aberdeen to Devon - and even New York - reported 'explosions' which shook windows and disturbed sleeping children at around 10pm.

One resident in Croydon, South London, recorded the sounds on her phone in a mystery that has left Britons blaming meteors, an 'alien invasion', 'the end of the world'... or just fireworks.
