Rough thumb calcs: Mach 6 is apx 3K MPH (4K True Airspeed but I’ll use the lower).

Cross the USA: 1 hour 15 minutes

Circumnavigate the globe at the equator: 8 hours

YMMV.

That is movin’ folks.

WTF is the difference between air speed and true air speed? Mach 6 is about 4,000 – 4,500 mph depending on the altitude. The speed of sound at sea level is about 760 mph, but it decreases with temperature. At 60,000 ft (where this thing will probably fly) the speed of sound in about 660 mph. That would put Mach 6 at 3,960 mph.

Thanks for the review. I was assigned at Edwards 1964-1968 and have forgotten some fundamental constants. I was there when Mike Adams was lost in an X-15. Mike was one of the brightest test pilots I have met.

imho . . .

from what my relative assured me . . .

we have craft that routinely go much, much faster than that

and have since AT LEAST 1970.

Anybody know how many G’s this places on the pilot - just in straight, flat trajectory, let alone in turns and dives?

Just curious...

On what grounds?

Reportedly, the fleets we have are built, now, by us.

. . . the critters having instructed us finally . . . in how to do it.

‘sweet’ bunch of satanic bustards, aren’t they.

BTW, have you ever heard how many personnel are in the secret astronaut corps?

http://en.wikipedia.org/wiki/True_airspeed

True airspeed is distinct from indicated airspeed.

Let’s see, it takes 17,000 MPH for a space craft(using the spin of the earth) to break free of the gravitational field of earth, I would say we already have craft that surpass the 6X speed and then some, of course if you are talking about every day use I hope those pilots have iron gonads.

At Mach 6 at an 87-degree bank angle, 3g turn probably closes the circle back at your starting point in about two hours; so that'd be a 1/3 of a degree turn per minute.

OK, so I'm only eyeballing that one without using the cackle-ator. Let 'em think we fly SOTP.

Most humans won't like even 3g's for anywhere near two hours' time. The better alternative, as was commonly known from SR-71 days, was just to go around the earth another time, with better planning next time.

1G .... from Earth. Objects in motion don't have G forces unless they are accelerating or decelerating.
