You think there’s now a 50% chance of boom bringing access to supersonic air travel to everyone? I’ll give them 10%.

Probably optimism talking, but I'd put Boom's chances of bringing to market an airliner capable of supersonic travel at equal-to-first-class-ticket-prices at 60%.

Now I'd put their wilder hopes of eventually taking over the subsonic economy market at considerably below 1%.

But I'm hopeful for that $5-10k ticket to London within the next twenty years.
