I have flown for 13 and a half years and nothing that has happened to be fair.
It is always said and cant remeber the stats but yur more likely to be hit by a bus whilst crossing a road than being in a aircraft incident.
Aircraft are so technically advanced now, your safe up there than on the bloody motoway.
There is a medication you can take which you can get from herbal shops for nerves.
Try this
Turbulence
You will be fine
