Supersonic jets do not have a place in the future, Willie Walsh, the former boss of British Airways, said, adding that he would not buy them if he still ran an airline as he dismissed a plan by United Airlines (UAL.O) to bring them back.

"I"m not convinced that supersonic transport is the right move going forward."
