If I happened to be booked on a flight that crashed and somehow I was deterred and never took it--I would take this as a sign from GOD and definitely re-think my life and change it accordingly. This would be a life changing experience let me tell you. I'm sure there are some in here that don't even believe in religion but I’m a firm believer and yes GOD gives signs to people everyday. Some people are blind and ignore it and some people see it.
God bless you all.
