BAM!: United Plans to Bring Back Supersonic Flights

United Airlines plans to buy 15 supersonic planes being developed by Boom Technology, hoping to resurrect high-speed flights more than two decades after that method of travel was grounded. United said it would buy Boom’s planned Overture jets if the plane meets safety, operational and sustainability standards. Boom hopes to fly a scaled-down prototype as soon as this year, with the full-size version targeted to carry passengers by 2029.
