I can't give deatils of any similar occurrence(s) as I have not 'wrriten up' the two that I intend to write about in the future. However, I can speak with knowledge of the two you mention because one of them directly involved me and both happened here in NZ. I wrote the article you quote, which was published in 'Rotor Torque,' the Heli. Club of GB's magazine. You precis of it is very accurate.
Full accounts of the occurrences described in the magazine article may be found on my website by selecting 'Occurrences' and then following the titles. Both are posted separately. (Web address is in my 'profile')
If there is sufficient interest in these accounts from other pprune forum members then I will arrange to post them directly onto this site under a a new thread.
Up to you ppruner's - If you want them posted, let me know.
Regards
SPS
