I've seen very quick irregular flashes from non-operational (tumbling)  
Iridium satellites, easiest to catch if
you lie in wait with binoculars. (No idea how many of these are still  
in orbit by now). Most passes would
give a couple of bright, attention-getting flashes, but often not  
enough to make out the tack with the unaided eye
without already knowing the direction of movement.
