Your fear of wings snapping is as irrational as looking at cars on the roads and wondering how axles can take the weight and why wheels don't keep snapping off? When was the last time you recall aircraft wings snapping off? Accidents do happen, aeroplanes do occassionally crash for some reason, but put it into context with the number of flights taken a day. If your number is up, it's up. You might as well sit back and relax and not spend your life worrying about it- spoil your life all the time for worrying about the extremely remote possibility of a very rare accident?
There's enough deluded people out there spending their lives worrying about being watched all the time by a mythical man with a white beard up in the sky and terrified of being judged at that moment when they finally pop their clogs! What a waste of time! Relax, enjoy yourself, follow your conscience and forget about 'deities'- they don't exist, forget about the extremely remote possibility you will be involved in a crash, the wings aren't going to break, the aeroplane is your tool for going from A to B, look forward to your destination and enjoy the view, or just get absorbed in a good book. Travel with the best- in your case it is a good investment. There's enough real stuff out there to worry about- road accidents, cancer, health, money. Don't add ridiculous things you don't need to worry about!
