Lightning inception

The knowledge of the initiation and propagation of an upward moving connecting leader in the presence of a downward moving lightning stepped leader is a must in the determination of the lateral attraction distance of a lightning flash by any grounded structure.

Studying aircraft lightning strikes

A very good article on

Lightning european project : FULMEN

FULMEN project :
Analysis of Experimental Data and Models for Upgraded Lightning Protection Requirements

This project created a database on natural lightning strike to aircraft.

As it is stated in this paper:
ALISDAR an Automatic Lightning System Detection And Recording
