I flew on a Ukrainian wetleased Yak-42 last year in Pakistan (Shaheen Airways). Weather was good.
As an SLF, only observed 2 differences from 'usual' flying:
1. Steep angle of ascent
2. Pilot did not appear to follow a constant bearing but continually made small adjustments. Possibly to avoid turbulence? (but I speculate)
pilot looked like an ex-mil type.
I chose to fly. The Spanish soldiers were not given the option. Poor guys.
hope this is useful (otherwise I will delete post)
