The nice thing about the 707 is thats it's as easy or as complicated as YOU want to make it. Some here like going through every detail to make it 'as real as it gets', and others like me just want to fly the thing and not spend an hour 'pre-flighting'.

For me, I just set trim and flaps, load a FS flight plan, and at 140kts I aviate, let Otto do his thing above 1000ft, then call the stweardess's to the cockpit for a 'chat'   :)
