If lightning is the build up of + charged ions (duh!) and so needs the - ( in respect to the + build up) to finish the circuit. Would turning off lights strobes really be an issue? Don't know the answer just posing the question.
I do know that in ground strikes the + actually "sucks up" a NUMBER (like multiple forks in a tree) of - bolts and picks the best / path of least resitance. So if "struck" by lightning the bolt actually comes from yourself and hence why multiple people can be struck, some suffering more than others. I wonder if this is the same with aircraft.
In any case, if you like golf, carry a 1 Iron. As, according to Seve Ballesteros ( I think it was him who said it ) "Even God can not hit a one iron"
