Boom Supersonic just flew its test jet for the first time as it races to build the world's new speediest airliner — meet 'baby boom'

• Colorado aerospace company Boom Supersonic flew its XB-1 demonstrator for the first time on Friday.
• Nicknamed the "baby boom," the jet tests technologies for Boom's future Mach 1.7 Overture airliner.
• The speedy Overture is set to enter service in 2030 and has already earned orders from airlines.

Colorado aerospace company Boom Supersonic wants to bring back the era of the Concorde — a beloved faster-than-sound passenger jet that flew for nearly 30 years before retiring in 2003.
