To find the cache you'll need to resolve the next puzzle
W : Planet = oO = 110 =1A = ?
X : Columbia = oOOo = 121 = B2 = ?
Y : Big Boy = ooOOOO+OOOOoo = 240 + 042 = (2D)D2 = ?
Z : Challenger = ooOOO+OOOoo = 230+032 = (2C)C2 = ?
N50° 5(Y-Z-(Y/X)).X((W+X+Y)/4)0
E004° 21.(((W+X)*Y)-(Z-W))/2+17
Have fun like always be discrete while searching and logging because there could be muggles at any time. Place the cache like and where you found it. Don't hesitate to log a DNF if you didn't find it so I can stay up-to-date and go check if there are some troubles with the cache.
NO SPOILER PICTURES, please!!
