Indeed they do, and that is to start 1 engine, there are 4 more on the
other side.

See the complete thread on rec.aviation.piloting for a great description
of the starting process.

I think I remembered incorrectly, looking at my photo it appears there were
only four "Dash 60s" (AM32A-60) used, all on the left side of the aircraft.
I'm thinking that the four "Dash 60" bleed air hoses were coupled onto a
manifold, and one larger hose went from the manifold to the pneumatic
starter attached to the underside of the engine. It's been a long time and
my memories are very hazy, but I think after the #2 engine was started, they
uncoupled the larger air hose and coupled it to a started on #1. Damned if I
can be sure though. I went through my photos and couldn't find any in which
the pneumatic starter wasn't blocked from view by a Dash 60. I'm a little
disappointed. Too bad we can't go back in time, so I could try to re-shoot
my photos or take notes or something...

Yeah - but then they'd have to kill you...

Didn't they use some sort of start cart with "Buick Wildcat" engines. I was
stationed at Beale AFB for a couple of years and remember something like
this.

Here's a link for SR71 Start Carts. I was right about the Wildcat engines.
