XB-1 went supersonic at the end of January [video posted this week]

Hope they got them down to 80 or 90 decibels.

Reached above Mach 1 three times with no supersonic db at ground level.

So, down to 0 decibels.

Fifty-six years late even if it went into service THiS year....playing catch-up with aviation history is not something that the US of A is used to doing.

And for sns3guppy, it was shitty runway maintenance that killed Concorde, not lack of engines.

Take off's count too, though

When it goes into service, will the pilot still be wearing a parachute?

That’s not the plane they plan to put in service.

Isn’t the history making part the lack of an audible sonic boom for people on the ground? Was the Concorde capable of that? The last time I saw a Concorde, it was giving rides to Canada where it was allowed to break the sound barrier over land.

That’s what you said and he agreed with 3 1/2 years ago.

some great cockpit videos shot during test flights - my favorite was the one where they deliberately induced flutter into the systems to see how it would respond

that some serious flying going on there
