    Will never forgetting getting marked down in that class for producing a square, when I was asked to produce a rectangle. "No, I meant a rectangle rectangle!"

    Actually, Concorde was too big : 100 seats. It worked NY/London but at ~$20k/seat they couldn't fill enough seats several times daily on other routes. Which means you can't have ma…

    There's computational fluid dynamics—which are very good today especially at supersonic conditions. Also, we have some design optimization tools we've built in-house which let us q…

    Speed: Mach 2.2 is the fastest speed possible with known technology already accepted by the FAA. At that speed, you can have good takeoff performance (and comply with airport noise…

    YC has been awesome and supportive in so many ways, far beyond money. 5 stars, would do again!! :-)

    Really good questions. We aren't sharing the details of the technical design quite yet (but will have more to say as we approach first flight). Regarding engines: our first prototy…

    We're baselining an experience better than domestic first class. One seat on each side of aisle, so everyone gets a window and aisle. There's more footroom and more headroom than t…

    Sonic boom physics are subtle and counter-intuitive. High level, you: (1) keep the airplane as small and light as possible (reduces total shock energy) (2) carefully shape the fuse…

    schwarrrtz and azernik nailed it. Today's batteries don't store enough energy for long international flights. There are some battery technologies in the lab (Google Lithium-air bat…

    TBH we really don't want to lock people out. I was disappointed that I never got to fly Concorde, not even once, and we want to open this to everyone (eventually make it routine).

    There's a lot of scorched earth in supersonics, since Concorde wasn't an economic success and the Boeing SST project was cancelled. Since then, there has been research on 300 seat …

    It's complicated and unclear, unfortunately. We'll have to see how things unfold when the airplanes are flying.

    We're teaming with existing and new airlines to bring aircraft into service. Posted ticket prices are based on what's profitable for airlines with the efficiency and performance of…

    $5,000 isn't an "everyone every time" price, of course. But it's low enough for routine business travel. With more innovation (this is just V1!), we can improve fuel economy and re…

    Supersonics help most on long international flights. So that's the first focus. San Francisco - Los Angeles, so much time is spent on takeoff and landing that faster cruise doesn't…

    Thanks! We are very excited to be doing this. We're starting out focused on long flights that are mostly over water, like New York - London or San Francisco - Shanghai. Around an a…

    Unfortunately, there's a ban on supersonic travel over land in the US since the 1970s. When this is reversed, we can fly SFO-JFK in about 2:20.

    We have the same gas mileage (fuel per seat mile) as a lay-flat bed in business class. Since the aircraft can do nearly 3X as many trips in the same time, on net it's better. That'…
