17:45 local 363.800 Mhz Had low-level 'fighter roar' overhead at 15 miles north of PHL. No visual or ID heard (didn't catch) but altitude changes reported. Altitude dropping and weakened audio heard.
I'm not showing anything for this frequency although I have it programmed. PHL ATC ?
Any ideas who this was ? Going into PHL ?
Similar when staging for flyover at Eagles game but only sounded like one A/C
