Hi Somasimplers,
Before 1990 Man thought he knew anything about thunder and lightning. He observed Nature and said: lightning is a negative discharge in ground direction. Industry protected planes in accordance and all went well but...
Some planes were abnormally destructed by abnormal lightnings. Their durations were too long and impacts too rude. But Man said it was hazard things without consequence!
But in 1989 was observed for the first time a lightning too long and its height was over all we knew => taller than 30 km with a 10 time duration in comparison.
Actually we know that is a positive lightning and some examples are 70 km tall! And its force is very impressive.
Here is a good source (see under research...)

We may, as Humankind thinks that we know absolutely all about anything and the next day, be more humble.
Health is a same mystery and we may discard all fanaticism and one way oriented thinking.
Keep your mind open and listen to all opinions!
