I had a terrible fear of flying - funny noises I didn't recognise, lack of control, not "understanding how the plane stays up", etc, etc.
Most people would have gone on a course or consulted a forum.... I took flying lessons.
When you're climbing out of Shoreham very very slowly in a 1969 (yes, I mean the year) single engined plane on which many of the guages and dials are "unserviceable" and the "instructor" is even younger and nerdier than you are it makes a Boeing 737 seem like the safest thing in the world. Of course it is - you have only to look at the accident records.
Genuinely worked for me

. Once you've flown the plane yourself the idea of flying through the air in a metal tube seems far less ludicrous. It's more of a subconscious thing.
All of the noises you hear (flaps, gear, etc) are perfectly normal including the occasional clunk/bang. Shortly after takeoff you'll hear and feel a reduction in power - again absolutely normal.
Slightly OT... I was on a flight from Malaga back to Gatwick a few years ago and the landing was quite rough (big crosswind). All of a sudden a young girl who had just lit a cigarette (!) 2 rows from me shouted at the top of her voice...
"We're all gonna dieeeeee!!!!!!"
And half the people on the plane screamed with her. It amused me but the cabin crew were less happy. I remember threats that the police would be called, although possibly more because of the cigarette.
