Airfrance Airbus 340 crash in Toronto YYZ

Note that the A340 is 100% fly by wire, so a lightning-induced computer failure (or even reset at exactly the wrong time) could cause a temporary loss of control, although the system is supposed to be hardened aganst that.

Interesting side note - aircraft are tested very extensively for lightning strikes in the air because they happen often. There were 25 in-flight lightning strikes reported to the FAA in 2000 from all US aircraft, from 747's to Cessna 172's. I'm not sure how extensively ground strike resistance is tested though.

Side note #2 - since lightning tends to come from a specific place in the sky, the slower an aircraft goes, the longer the strike will last (generally.)

"a spokesperson with the Greater Toronto Airports Authority said lightning was causing technical problems with the airport's lightning-detection system."

So how does that work? What is the point of having a detection system which fails when it starts to detect what it is looking for? And what is a lighting detection system - a small child and a large window?

Glad no-one was injured.

Are these reports for lightning strikes that caused an emergency landing or strikes total. 25 seems kinda low since in the last month we have had 9 planes in the hanger with lightning strikes and I have gone on 3 road trips to rescue planes that were hit by lightning at outstations and these are just the one's when I was working. Dont know if any happened on my day off. Just wondering.
If you find yourself in a fair fight, your tactics suck!
