Thanka again sincerely to everyone who has responded and you encouraging words.
Wow, some of these 747's that could be flying to London are 20 years old. I must say I find that scary. I suppose they are maintained well as you have all said. I didnt think they flew aircraft that were that old, in the case of Qantas.
I cant help thinking that:
1 that is a lot of take offs and landings and stress for the plane.
2 I reckon most people dont even bother to know what year the plane they are flying is, they just get on and go.
Unfortunately in my case I just find it overwhelming. So much so that people at work have been commenting that I really look ver very stressed. Why, I dont know its a really big step for me and yet I ride a motorbike without too much fear (most times). Maybe its just my nature.
