The headline is misleading. It’s quieter, but far from silent.

sonic booms quieter than a hairdryer

More like about one specific noise. Jet aircraft are generally pretty loud even outside of sonic booms.

Hairdryers are quite loud too. It’s a stretch to describe even the sonic boom as “silent”.

Aren’t they fairly quiet to the passengers?

(the sound being behind the plane)

X doubt

Aerospace needs effiency not speed.

Given that this is being developed by COMAC which is a state owned company, I absolutely expect that it will see the light of day.

The problem is that the only way to do this is by using rocket engines which are extremely polluting. There would need to be new motor innovations which can be used for every field. Iike a small nuclear motor or the like.

I think we’ll have to wait and see what they actually come up with here.

Scheduled to debut in 2049

Gonna be a long wait
