HC, I agree with what you say, but I believe the odds to be striken must be higher if certain conditions are met.....
Where I use to fly, OAT is usually around Std+15°c and never less than 18°C at our levels. It just makes sense to me to avoid places where lightning activity seems to be the strongest. I also know it is not an absolute vaccine but it should look a little provocating to fly right trough it....Some of those ancient Gods barely allow us to fly, no need to challenge them !
As for possible damages,I have read in an old lightning strike thread, that a German BO105 had its blades destroyed in flight by a lightning.
