I just witnessed the Pegasus/SWAS launch in crystal-clear skies over
southern California.  It was much more impressive than I had expected.  It
seemed to come toward my location in southwest Riverside County rather than
following a more tangential path that I had anticipated.  At a certain
altitude a contrail formed (the remnants of which still persist 30 minutes
after the launch).  At higher altitudes the pure white plume spread widely
and dispersed without forming a contrail.  Engine burn-out occurred
southwest of me at about 35 degrees elevation.
