REUTERS/Denis Balibouse (Reuters) - Boeing Co-backed supersonic jet maker Aerion said on Wednesday Berkshire Hathaway’s private aircraft firm, NetJets, has obtained purchase rights for 20 of its AS2 business jets. The AS2 will be powered by engineered synthetic fuel and can reach supersonic speeds of up to Mach 1.4, or about 1,000 miles (1,610 km) per hour, which is 50% faster than conventional business jets, Aerion said. Production of the jets will begin in 2023 at the firm’s Aerion Park facility in Melbourne, Florida, with the first 300 AS2 aircraft planned for the first decade of production, the company said.
