I guess the difference is the Bloodhound is piloted and, in theory, can be deployed at a (very) few sites, while the Holloman sled is tracked and unpiloted, thus the Bloodhound is a test of skill, planning, and courage. Or something like that.
At least the Bloodhound driver is an RAF wing commander Larry!
I seriously wish them well, and their vehicle is awesome cool!
and I will look at it with interest.
But don't forget what Holloman has done! I certainly won't !
And don't forget Col. John Paul Stapp, who went 632 mph
in Dec. 1954: 0 to 632 mph in 5 sec, and 632 mph to 0 in
1.4 sec!
Few people know that Col. Stapp was planning a 1000 mph run
in "Sonic Wind" in 1955 or so. The USAF axed that plan though
because they didn't think their sled technology was up to it then,
and they were also worried about Col. Stapp's health.
Turns out that Stapp lived to the ripe old age of 89 after 29 rocket
sled rides (he died in 1999).
Back to Holloman's Mach 9 achievement.
I would actually like for USAF to also use their hypersonic sled for
human acceleration tolerance improvement study. But there is
no mandate for that currently that I know of. And who knows
if there ever will be given the probable state of future advanced
aircraft development being for unmanned vehicles.
