Replying to a message of Adam Flinton to Phil Payne:

 AF> From: "Adam Flinton" 

 AF> I thought that the only 2 seat sr71'es were trainers.

I think the trainers were called YF-12's.  AFAIK, *all* SR-71's
carried a pilot *and* a navigator; during my last AF assignment I worked
for an AF LC who'd been a navigator in the SR-71 program.
