Heathrow could get sonic boom 'every five minutes' from fast jets

Supersonic aircraft would bring noise and greater CO2 emissions, report says

Heathrow airport could be hit by a sonic boom every five minutes as a new class of supersonic aircraft come into service, research suggests.

It is predicted that by 2035 there could be demand for up to 2,000 supersonic passenger jets, which could knock hours off long-haul trips.
