Older aircraft mixed flight spoilers mechanically. Newer aircraft with fly by wire spoilers may give the aircraft the ability to give greater authority of flight spoiler over ground spoiler. The one spoiler on the left wing you see up may be design spec for the aircraft.
747 wing - this aicraft is amazing at aerodynamic breaking. Used to love watching skilled aviators ride that nose to the ground. As I understand the wing is more effective than the TR's at inducing drag to a certain speed, just a risky task.
I have to add my two cents here that the thin skinned haters who think their career is worth more than a cookie need to chill out a bit.
There are people here who seek knowledge and people who simply want to state their oppinion, It makes this board a great thing.
