To find the cache, first you must locate the airplane. To do this, you will need to use the 'Historical Imagery' button set to 2004!
Once the airplane is located, you will need to measure 294 meters from it's nose at an angle of just under 90 degrees (87.8 to be precise). It is here that you will find parking and the cache. I have added a geochecker 'just in case'.
