Virgin Atlantic's Founder Richard Branson-backed startup Boom has unveiled a supersonic jet-prototype named 'Baby Boom', that covers 5500 km distance between New York and London in just 3.5 hours. A passenger plane usually takes at least 6.5 hours to cover the same distance. With a capacity of 44 passengers, the jet will be launched in 2020 for ₹34,000 a ticket.
