Yesterday afternoon (May 19) I was sitting in Pittsburgh at gate C51 (I believe) in Pittsburgh waiting for my flight home on Midwest Connect. While watching planes come and go I noticed a UA flight 973 to Chicago depart from the gate next to C51.
I noticed the red strobe light (both on top and bottom) wasn't on. It pulled away and taxied out of view still with no strobe. Would this be a case of it being burned out? I can't recall ever not seeing a strobe not on while an aircraft was in service. Any thoughts?

Don't know if the flight you saw forgot to turn it on, or whether it was inop (I suspect the latter), but the aircraft can operate with both red anti-collision strobes inop in day operations. If the aircraft is also equipped with white strobelights at the wingtip/tail, the aircraft can also operate at night with the red anti-collision strobes inop.

When I turn over an aircraft to depart my gate I always watch BOTH the top and bottom red ac lights. If one is out I note it in log and if both are out I have our control contact the crew for notification. It's nearly always just an oversight but I wait until the aircraft is ready to depart the ramp area onto an active taxiway before calling. That gives them any "rolling checklist" time.
