That's not quite the case, Pat. The A-12s could be equipped to handle a single
mission - Wide field photo, narrow field photo, SLAR, or ELINT.
The Air Force figured it was better to equip the SR-71s to be able to handle all
of them. While that meant they couldn't haul the Great Big Camera, they were

Actually, there's in interesting angle here.
"Public Use" aircraft - aircraft owned and operated by government
agencies (Even State agencies as opposed to Federal) are considered
outside of the FARs. (Among other things, this allows military pilots to
fly without FAA civilian pilot certificates, and military mechanics to not

Difference being that Germany was the aggressor in its attack on Europe
and the Soviet Union; nobody attacked Germany first and then got invaded
by them in defense.
Then there was setting the precedent of terror bombing of civilian
targets, which the Luftwaffe had set clean back in the Spanish Civil War

If NASA astronauts are aboard, then it should be NASA who decides if
it's safe enough for a NASA crew to fly. Others may prefer the FAA,
but you can bet Congress will insist on NASA safety reviews and
oversight if carrying NASA astronauts. Besides, how much spaceflight
experience does the FAA have compared to NASA?

It is apparent you're not acquainted with rocket science. Getting through
the "dense lower atmosphere" is no big deal. Von Braun did that with an
single stage alcohol fueled rocket 65 years ago.
The problem is getting up to orbital velocity.

Try checking out some of the Articles in "Air Trails" from the war
years, especially 1942 and 1943. They were talking about how the
Luftwaffe was flattening every European city that resisted - and what
was going to happen to them as well.
Propaganda is propaganda, no matter who writes it....

They take real glee in describing the Luftwaffe laying waste to cities
in the countries they are invading.

city center reduced to a mass of burnt rubble:
"THE SPECTACLE OF 'TOTAL' WAR.
After Warsaw, it was Rotterdam that, issuing a challenge, learned how

Because 50,000 feet gets you above the bulk of the atmosphere which provides
a decent bonus.

the hardest part is having enough fuel onboard to get you thru the
dense lower atmosphere.those large tanks weigh more.
with a aircraft first stage that part is taken care of by a mature
well understood technology, and since in air refueling to release
altitude would be used lots of unnecessary mass wouldnt need lifited

Why do people think that launching from 50,000 feet will help somehow?
Going into orbit is not a matter of going high, it's a matter of going
_fast_. Launching from 50,000 feet or from sea level you still need to
impart 18,000 miles an hour of delta-v. That's the hard part.

launch costs would tumble.........
