Aurora's main business is in advancing the world of military aircraft, and has won several contracts from NASA and DARPA. Most famously, the company won funding to build phase two of the VTOL X-Plane -- beating out both Boeing and Lockheed Martin. The VTOL X-Plane (codenamed LightningStrike) promises to achieve top flight speeds of up to 400 knots with a more efficient hover and lift-to-drag ratio.

It's believed that Boeing will buy the company to help bolster its own expertise in autonomous aircraft and VTOL technology. It's likely that the bulk of that knowledge will be used to develop military vehicles, although we can hope that it will also trickle down to drone taxis and the like. It's not clear how deep Aurora's relationship with Uber went, or if that deal has ended now that Boeing is in charge.

The deal is structured so that Aurora will exist as an independent subsidiary under the Boeing brand, although without direct control. Although it's worth saying that the company will have access to the aerospace giant's vast R&D and financial resources.
