I was on approach to Vienna yesterday evening when I observed two 2-second green laser flashes 5 seconds apart from one of the rear passenger windows of the B737 where I was seated being pointed at the aircraft.
I'm wondering if and what I should do since green lasers are dangerous, and I'm convinced the aircraft was being targeted. Should I report this to the relevant authorities? Is it very common or a rare occurrence? The co-pilot didn't seem very bothered about it in any case and he hadn't seen it.
20th December 2014: Sent an email to the relevant Austrian authorities. Will see if I get a reply.
22nd December 2014: Sent a report to AustroControl as well.
