My Master's thesis included a large amount of information regarding N709PA, Pan Am Flight 214, en-route from Baltimore-Friendship, to PHL, on the evening of December 8th, 1963, when it was struck by lightning (in midair) near Elkton, MD, and crashed - killing all aboard.
The (full version of the) CAB report listed three pages of info regarding "the possibility of aircraft induced electrical activity", which may be of interest to some of our more science-minded forum members.
A very well researched .PPT presentation about the tragedy can be viewed
