SIGHTING: VILLANOVA, PENNSYLVANIA (UNITED STATES)

Witness Testimony

"Red and green lights look very much like a plane, but could not hear sound. lights blinked off and on, but somewhat out of sequence expected from a plane or helicopter. lights were moving south west but stopped when i saw them. the green light spun around and it started flying off in the opposite direction changing from sw to ne very quickly. flew cross major phl flight path. no ads-b signal and no sound could be heard. if this was a helicopter, it did not move like one. moved like a drone, however was too bright, too high, and no sound could be heard. observed small and commercial plane flying in relatively the same airspace 5 minutes after sighting. both planes were substantially dimmer than the red and green lights on this craft. most likely this was a drone or helicopter, however it is hard to believe it was a helicopter which i've seen many, many times as we are on the phl to west chester medivac flightpath and this wasn't one of those. ufo sighted approximately where the yellow plane is on the ads-b map, however, no plane or helicopter appeared on the map during the sighting moments earlier. both planes in the screen capture were visible and audible, unlike the red/green drone/ufo. ufo also took off in strange direction, not common for aircraft or medical or news helicopters returning to phl or northeast."
