A number of years back when it was located in my home patch I "landed" (or should that be crashed with style?) the BMI 737 simulator on the grass at Dublin. I can safely say that I'm either totally useless or it's pretty difficult - even with someone telling you what to do sitting by your side!
The same guy then took me on a trip to somewhere in Japan (I think) and proceeded to fly the thing through an open hangar door and out the other side which kind of put my efforts into context!
