I was on a plane a few mo's back (sometime earlier this year don't remember exactly which one)...
Anyway lightning hit the plane. Saw a bright flash, and heard the noise, and pretty much that was it, plane did fine. Still scared me but I guess it happens frequently enough and it's not really an issue. The takeoffs and landings can be a bit of an issue so sometimes they'll reroute to a different airport of weather is an issue, they are pretty conservative about those kinds of things so I tend not to worry about it.
