as you are having difficulty thinking beyond your normal enviroment i will spell out a few points you may not be aware of
1: aircraft need both pilots to be fully on form when completing the most dangerous part of flying ie landing
2:why? well it is quite busy in the cockpit prior to landing there are lots of things to monitor ,mainly height,speed,attitude,rate of desent, heading,remaining fuel,talking to air traffic and lastly comunicating with the punters in the back.
3: If there are any doubts they have to over shoot and get in the queue to land whilst working out how much fuel is left and where the diversion landing is and if it is available.
4:So having some muppet shining a laser at an aeroplane with 200 plus people is a serious offence and is dealt with accordingly by the courts.
Aeroplanes may be just another method of transport but to run safely they are complicated animals as many people have found out to their cost.
