I saw a nice photograph circa 1996 of Helikopter Services chief engineer at Bergen with his head through a hole in a Super Puma main rotor blade post lightning strike.
Was not the loss of Bristow S76 G-BVJX that crashed out of Norwich about 2002 put down to undetected damage to a main rotor blade caused by a lightning strike?
