United Airlines (UAL  ) announced last week that they plan on making a commercial agreement with aerospace company Boom Supersonic. The agreement entails that United Airlines will buy 15 of Boom's "Overture" airlines, as soon as Overture meets United Airlines' safety, operating and sustainability requirements, with the choice of an additional 35 aircraft.

The two companies will collaborate together and work on meeting the requirements before delivery. Overture is anticipated to be the first large commercial aircraft to be net-zero carbon from the first day of operations. It is likely predicted to come out in 2025, fly in 2026, and carry passengers by 2029.

United Airlines and Boom will also collaborate together to speed up their production of supplies.

"United continues on its trajectory to build a more innovative, sustainable airline and today's advancements in technology are making it more viable for that to include supersonic planes. Boom's vision for the future of commercial aviation, combined with the industry's most robust route network in the world, will give business and leisure travelers access to a stellar flight experience," United CEO Scott Kirby said in a press release. "Our mission has always been about connecting people and now working with Boom, we'll be able to do that on an even greater scale."

Overture has quite an impressive speed and swiftness that other aircraft do not have, able to fly at speeds of Mach 1.7, which is twice the speed of today's fastest airliners. It can also link more than 500 places in about half the amount of time. Some of the possible destinations and routes for United Airlines are Newark to London in three and a half hours, Newark to Frankfurt in four hours, and San Francisco to Tokyo in six hours. Overture will also contain features such as in-seat entertainment screens, a great deal of personal space, and contactless technology.

The pact that United Airlines has made with Boom Supersonic demonstrates the "future of commercial aviation," ultimately providing an experience that connects people to their destinations faster than ever before.
