Someone has probably mentioned this already in the thread but I am too lazy to read the whole thing...these laser "attacks" happen daily when approaching into GRU and GIG (sao paulo and rio de janeiro). The ATIS even warns of possible laser light aiming at the airplanes on approach.
The first time it happened to me I reported it, and the tower replied like they already knew.
What surprises me tho, is that the laser they use is green (as opposed to the little red laser pointer I use to convince my cats to get back in the kitchen when it gets dark) and seems very powerful.
Cheers.
