Night landings are, by their nature, more difficult and more dangerous than daytime landings. Assuming visual conditions, nearly everything is dependent upon being able to continuously see runway lights. About 10 minutes prior to landing, the standard procedure is to dim everything in the cockpit to it's lowest setting. The goal of this is to make sure the pilot's eyes are dilated as much as possible to see the runway lights and land safely.
About 5 years ago, I was landing at Chicago Dupage airport. About 1 mile from the runway threshold and about 500 ft above the ground, I was repeatedly hit by a bright red laser. Immediately after the first bright flash from the laser, I felt like I'd just walked from daylight into a dark room. I couldn't see anything. I couldn't see any instruments (Remember, they're all dimmed as low as possible) and the runway lights were suddenly very dim. After the second and third time, I couldn't see the runway lights anymore. My only choice was to add power, pull up and hope that I was still flying straight. I overflew most of the airport and remember finally getting good vision back about the time I was over the subdivision north of the airport. That subdivision is about 3 miles from where it all started. I turned over the subdivision and landed on a perpendicular runway.
I then released a torrent of profanities and considered all of the most painful ways to kill someone if I could ever find the #@(#*$@(#*$@(*##$(@* that hit me with that laser.
I'm all for higher penalties for this crap. It's probably already killed people. We don't know for sure because plane crash victims don't tend to be very talkative.
