Just looking for a friends flight on http://planefinder.net/ and up popped a supposed Britannia Flight over Pula.
It actually was flight number BAL526, it said Britannia Airways oddly but in typing the flight number into Google it comes up as Belle Air Europe 526 from PRN (Pristina) to VCE (Venezia Tessera). Aircraft Reg No. EL LIR
I wonder what planefinder is doing having a defunct airline in its indexes?
