If you engineer get ahold of the rocket boots extreme [300% speed for 5 seconds] and go to nagrand. Theres a quest with a trampoline that you get to keep the key to after the quest is finished. Use the trampoline to get a 3 min slowfall. Once you land jump on your flying mount and fly up as high as you can. Now start flying north for a few seconds and pop this macro.
/dismount
/use rocket boots xtreme
If done correctly you will rocket clear across nagrand.
I recommend you have a slowfall cape on just in case slowfall breaks before you land.6):
