I too have seen these shockwaves, quite different from the
condensation effects.  I remember standing by the control tower at
Farnborough during practice before the air show some time ago when a
military jet did a fast low pass.  The shock wave was clearly visible
and extended 8-10 feet above and below the aircraft.  The noise was
also noticeable!
I have also seen the Green Flash (from an aircraft flying from Nadi
due South at dawn).  But what is the Blue Jet (pardon my ignorance)?
