Boeing 2707 is a supersonic airliner project developed by Boeing in the 1960s. Being the most advanced of all supersonic airliners created at that time (Concorde, Tu-144), Boeing 2707 turned out to be too complex to implement and was not created. The project was closed. The planes never flew. Subscribe to the channel, comment, like! Skyships Boosty: https://boosty.to/skyships Our VK group: https://vk.com/public123681709 Instagram: / karen_skyships
