Oh my lord this is pretty crap!
First episode starts off ok and the bits on the aircraft are ok, ish but the bits on the ground and particularly the air traffic control scenes are just utterly awful, embarrassing and factually incorrect, and that is putting a positive spin on it!
Unless you have no knowledge of real life, are an utter imbecile or have the ability to suspend your disbelief to previously unthought of levels then do yourself a favour and give it a miss
