Sir Cumference,
Thanks for a great update.
I must admit the "rolling" of the 407 is a worrying fact to me as well.
Being an "old bold' pilot - it aint good for any youngsters to see this - especially if illegal.
I remember in 94 when I was asked to roll a BK 117.
I went through the correct channels and DCA dis -approved as Lansav dis - approved and of course BK dis - approve unless changes on the tail boom was made (cutting of the vertical stabilizer if I remember correctly).
Well CAA reads this and I am sure they will have something to say ...
