Some years ago I took two colleagues along on a 733 sim ride for a treat. Both were aviation maintenance people but neither had any flying or previous exposure to a serious box .. but both were mad keen FS fanatics.
I gave each a go in the box (motion off) and each flew very creditable I/F stick and rudder work, including an ILS and landing. Certainly enough to impress me ....
.. and both of these chaps were in their 40s ...
