Colorado-based Boom Technology has raised $33 million in a Series A round to build and fly its first supersonic jet, a one-third-scale prototype known as the XB-1 or “Baby Boom.” Testing the XB-1 would blaze the trail for a full-scale jet capable of taking 40 passengers from New York to London in less than three and a half hours for a $2,500 one-way ticket.
