F16? F18? MIG 29? *tornado*!

hi,
out of the four which is the crappest? and oldest for that matter? OBVIOUS! when i join the RAF, and hopefully become a pilot i will “*probably*” be flying that wreck! I DEARLY HOPE THAT THE RAF BUY THOSE EUROFIGHTERS SOON! SO I CAN HOPEFULLY GET TO FLY ONE! i need to know what exact year the RAF are buying them?

thanks, G-FORCE
