It's called IFR or Instrument Flight Rules. It pretty much means flying using only the instruments for situations where you can't see anything outside the plane. It is possible to land a plane using nothing but instruments.
Also, large commercial planes like that have autopilot systems capable of landing the plane with no help at all.
IIRC only the most modern planes like the Airbus A380 and the latest
Boeing have autopilots than can actually fly the plane all the way down
to the ground.
In every other plane the pilot has to fly the last 200 feet or so of altitude
by hand.
If there isn't enough visibility, airports don't let anyone land.
Even if he isn't blinded by the flash, he is very busy at this time.
Watching airspeed, keeping roll and pitch steady, correcting for
crosswind, preparing for reverse thrust, etc. etc.
The pilot doesn't need ANY distraction at this moment.
Will he crash the plane? Probably not.
But even a go-around isn't something you just do for the lolz.
I also beg to differ on the whole "constant wave-autofire" argument, ....
Maybe I didn't explain myself properly, what I meant was:
The flare gives you one shot. You'd have to be an absolute crack or
get incredibly "lucky" to score a hit on the cockpit's windshield.
The 200mw pointer almost "guarantees" you a hit if you scan it in the
direction of the plane long enough.
Well at least it's much more likely to eventually flash the pilot than with
a one-shot flare.
