The cache is NOT at the given co-ordinates, you will need to solve the puzzle in order to obtain the correct ones
Continuing with Tigger's Tricky Trail and a Puzzle this time but don't worry, this won't be testing your schoolboy french, but might just help with that Alphabet Challenge you've be working towards.
My first attempt at a Wordsearch - note that individual letters may appear in several words!. Simply find the names of the aircraft listed - there will be two unaccounted for. Take these two names and convert them into two 10-digit numbers and enter those into the Checker as X:Y and the Final co-ordinates will be revealed.

certitude.
