>Boom's first commercial super-fast plane, called Overture, hasn't been built yet, but it's expected to be operational in 2025, take to the skies in 2026, and carry passengers by 2029, United said. Overture could become the first big commercial aircraft to be net-zero carbon, and will run on fully sustainable aviation fuel, according to United. The supersonic jet, when built, will be able to fly twice the speed of the fastest airliners in today's market, cutting some flight times in half, the American airline company said Just gonna call bullshit on a majority of those claims.
