I hope we learn the lessons, the instructions on the aircraft is for everyone's safety.
I have seen people walk even before the seat belt signs are off, or switch on their mobiles till the take off and at the touchdown.
These guys not only jeopardise themselves but everyone else in the aircraft.
If they are such biggies that they cannot stop to communicate or the world would come to an end without their communication they must start chartering aircrafts.
Even domestic flights we must be a lot more careful.
