Stars visible from aircraft ?

I found this URL :

but it is *not* my experience.
Even with my camera I took the stars with the wingtip light on.
When the cabin is dark (usual during nightly long-haul flights when no meals are served) stars are easily visible despite the rather poor window quality.

I can recall one night when I flying over Los Angeles and looked out the window. I could see the southern cross, which is not normally visible from that latitude.
I think that this is not possible. Crux is between 57º and 63ºS so it is not visible from LAX (34°N) even on 11km altitude. At that altitude the horizon is lowered by acos(6378/6388) = 3° which allows seeing objects till 59°S declination so only Gamma Cru is displayed znd not the entire constellation.

What are your opinions / experiences ?
