essouira,
First, I'd like to say that I recent your tone, which is ridiculing and full of disbelief.
What is it about you people ?! It seems that your credibility around here equals to Zero in some people's eyes if you don't have an ATPL. Sheesh...
I will not write an essay of those incidents here, but I will tell you this.
All of them were failures of PURELY mechanical nature, and neither me or my father (who was PIC) could do anything about it.
To be more specific, the magnetos were malfunctioning in a way that the engine didn't ignite constantly as it should have. And due to this it lost power. We had to do an emergency landing back TO AIRPORT each time, so I have to disappoint you: no burning wrecks, no victims no nothing. Just a couple of shaken persons with a lot of questions. And I can tell you this, it is not pleasant to encounter these at night...
Fly safely!
cheers,
Tero
