? I don't agree that flying is a sfe way to travel. Only one accident causes a lot fo injured persons(some accident are not) 

 First, plane crash is a big disaster. It's rare, but when it happens we can not ignore it. 

 Second, flying travel  causes ear pain. Otalgia is due to change of atmospheric pressure. Some peole get less influece but other people get more influence. IF you are the latter, you can suffer form sequela(후유증) ollowing/after plane. Like a buzzing in the ears or ear fullness. These symtoms last for 3days, make problem for our life.  

 The percentage of happening of plane crash is very low but preparing for small percent is not a big problem.
