| Subject: | Re: Yak-List Digest: 9 Msgs - 04/02/10 |
So it seems to me that if yak 50 owners arrange a suitable programme to xheck the
airframe, prolonged lifetime will not be a problem. Also the yak-50 have a
lifetime on 13000 aerobatic cycles/manouvers. Should this not be evaluated in
the same manner?

| Subject: | Yak 52 in the movies... |
Hey all.....sorry for the off topic post, but this is cool...
I have been watching / following the Resident Evil movies series from
the beginning, mainly because the main character was played by Milla
Jovovich.....and now, in the latest sequel; Afterlife, it looks like a
Yak 52 may steal the stage (even if they got the sound wrong in a
couple scenes)! Gotta love it! ...Also, Ali Larter is also in this
one, and I really like her too!
Check out the trailer...
