Re: "Test flights in January proved out the concept [of Boom Supersonic]"
> It probably can't financially work if the only market is commercial aircraft. The decrease in flight time is overwhelmed by the total trip time when you count the trip to the airport, security theater, waiting, boarding, taxiing, then taxiing, deboarding, and waiting at baggage claim, and trip from the airport. Maybe it makes sense for long haul e.g. LA to Tokyo but again it will be much more expensive than regular aircraft.
A lot of that stuff goes away when you travel business though. You can get things like TSA PreCheck (minimal security based on a background check, you skip the line), you'll have a limo to the airport, express check in to board quickly and you can bet the premium airlines will be paying to get the best slots so they depart quickly. Money makes a lot of problems go away.
For economy class yeah, it almost certainly won't make sense, but Boom have been pushing their product as a business class aircraft only.
