G'day Paul,
I had the jokers take my keys and leave.
Funny men! Very funny. I laughed lots and lots and lots. NOT!
The lucky thing for me, it being an ageing 182, was that he didn't (in his haste) actually turn the mags to 'off'. He just pulled the keys directly out with the mags in 'both' and I was able to conduct a normal descent.
It just happened I'd been offered a job at a neighbouring flying school and was planning to resign that weekend.. so when I landed I calmly strolled up and quit and informed the chief jump instructor I would be contacting the police regarding attempted murder. ( a little over the top I know - but considering what the consequences could have been..)
The jumper in question was banned from the club.
I wanted to knock his block off but that would have made me the bad person.
Turns out all the other jumpers were horrified at his actions and were quite pleased to see him gone.
99% of them are good fellas/ladies.
cheers Ibol
