I am currently listening to the KJFK tower feed and around 1:15/1:20p on 2/24 someone with a heavy accent contacted the tower with the callsign Kayak-52. It caught the controller off guard for a second and after reading landing instructions he asked the pilot to confirm the callsign. Upon landing, the controller instructed him to "follow the car with the blinking lights". Anyone have any clue what Kayak 52 was/is?
