I worked in a lab and we did work on military aircraft and had reports on lightening strikes.
Lightening is a complex phenomenon. Often there are as many as 6 individual bolts going up and the down and back up again, one after another reversing the direction of current. Often the first leaders just ionise a path for number two, but the subsequent ones only approximately follow the prior one, and an airplane can fly through a lightening bolt and only be hit by one as it moves out of the way before the next one hits and often they are hit in the cockpit and it exits from the tail. It pays to have good conductors built into the pane to take the current rather than it going down your system wires. Often the first leader goes up and creates the path down.
