Lightning
<quote><snip>
Anyway if I could reassure Steelfo by stating that every commercial aircraft flying has or will be struck by lightning at some point. It is very rare for that damage to be severe enough to loss of control or a crash. In fact I can think of only 1 case off the top of my head and this involved small commuter aircraft. <snip><close quote>
I believe that in the early days of the B707 a crash of a PAA flight in Maryland was blamed on a lightning strike.
