Le Pen, Starting rumours? Static discharge wicks are not lightning strike dissipators. They are not always capable of dissipating static electricity much less a lightning strike.
I have been in aircraft that were hit by lightning in flight. One strike left a hole in the top of the rudder big enough for me to put my hand through. There were also about 20 small, pin prick, holes in the wing tanks and most of the avionics were damaged.
I saw a Beechcraft get hit by lightning on the ground. All the lights came on for a few seconds. The lightning came out of the propeller blade closest to the ground and blew a small hole in the asphalt. I was only about 50 feet away from it at the time.
Yes, in the US ground personnel are supposed to stay away from the aircraft when there is lightning in the area. The southeastern states, especially Florida, get a lot of lightning. The spring and summer months are the worst. People are killed by it every year.
