Olympic Airways ATR-72 had an engine fire on the runway and then (due to the engine systems) apparently couldn't get off it . - was also allegedly a crew training flight according to the agent!
Caused utter chaos - happened about 0800z , airfield open approx 1400z. My lot ended up in CFU but managed to get back to UK in a duty day plus a bit of discretion.! This is what probably accounts for YOUR charter flight being late today in the UK!
