Afaik, lightening of whatever type is not a significant threat to airplanes. The bolts travel through the outside of the metal body and the charge is leaked off through trailing wicks.
TWA sold several of its 747s to the Shaw of Iran circa 1974.

One of them exploded on approach to Madrid. It was determined that it was lightening that hit the wingtip and went into one of fuel tanks through the tip vent.

After that TWA, and I presume other airlines, installed lightening suppressors in all those wing tip vents.
