Sorry don't know the ATC jargon for the routes out of MAN
but I saw the Hercules on Sunday directly over here (near Handforth station - check Multimap out for the exact location) having already turned and heading south. This is way sooner than any jets do, I sometimes see those from here but they are much further east and much higher than the Hercules was, confirming what Jamo said about the early turn.
I saw a Hercules taxiing, presumably having just landed, on Sunday morning when I was at the viewing park, around 10.45am. I also saw another (same one I guess) on a similar flight path to the one in the evening, albeit much higher, during mid-afternoon Sunday. Any idea what it was doing in the area? I assumed it was making an appearance at an airshow/event.
