In a joint ceremony with Lockheed Martin Skunk Works in Palmdale, California, on Friday, Nasa revealed the X-59, an experimental aircraft that is expected to fly at 1.4 times the speed of sound – or 925mph (1,488 km/h).

The aircraft, which stands at 99.7ft (30.4 metres) long and 29.5ft wide, has a thin, tapered nose that comprises nearly a third of the aircraft’s full length – a feature designed to disperse shock waves that would typically surround supersonic aircraft and result in sonic booms.

These kinds of comments only say it’s wrong; they never make a valid contribution to finding a solution.

The guy you're replying to or the nonce suggesting we shelve all transportation technology and only use trains?

The nonce, of course.

Oh good, he has too many upvotes for me to assume but I figured.

It's such a shame, you'd think these communities would be about how advancement is always good due to it unlocking new possibilities. For example, maybe this aircraft will open up doors in hypersonic flight that could be used to make more efficient SSTO model and get us less dependent on fossil fuels for chemical rockets via traditional means. Or allows materials science to make a leap forward that revolutionizes fusion.

To just say "why are we doing this?" Is an absolutely insane perspective for R&D and a fundamental misunderstanding of the way we develop technologies.

I think part of the issue is that the fine granularity of Lemmy (or the other place we don’t speak of) doesn’t lend easily to broader topics but instead seems to pull in “only THIS” or “only THAT” binary thinking. Only bikes or only trains or only trams doesn’t help when you need to cross continents.
