Many uninformed comments are worrisome. For those non pilots please understand that once an air carrier flight which had filed an IFR flight plan becomes airborne, that flight plan is submitted to all ATC on the route of flight as well as the destination. In addition it is most likely that the aircraft was sqwawking the last issued transponder code. Also I would assume that ADS-B out was operating. All regulatory agencies therefore knew which aircraft they were tracking, its position, its altitude, its destination and its ETA. In the absence of COMs, ATC had to only provide seperation for the aircraft with which they had voice contact. No big deal and certainly no need for military interception! 10,000 tt, COM., SMELSES, A&P/IA
