Flightradar24 is tracking an aircraft marked as Kenyan Air Force Alenia C-27J (222) departed from Istanbul southbound.
But its hexcode (C9D52F) is this one of a Turkish Air Force Lockheed C-130, the aircraft that made the flight Istanbul-Misrata-Istanbul on Thursday and Friday.
So in all likelihood this aircraft is the Turkish Air Force Lockheed C-130E (71-01468) and probably is making a new flight to Misrata.
UPDATE – 18:45 CEST
A second Turkish Air Force Lockheed C-130E (63-13188) is leaving Istanbul, also the destination of this aircraft should be Misrata.
Now we’re tracking two Turkish Air Force Lockheed C-130E (71-01468 & 63-13188) probbly directed to the Libyan city.
