Do not go to the above coordinates unless you want to stand on the tarmac at Terminal 5. Although what you see there on Google Earth might help.
I got the idea of doing this cache from a similar one at Gatwick Airport. It took me a little while to relate the puzzle to the aircrafts, but once I twigged on to what I had to do the puzzle was relatively easy. So good luck! I have put difficulty rating slightly lower to the one at Gatwick as I have given you a bit more of a clue.
Difficulty 3.5
Terrain 1.5
Just so those cachers who are not into aeroplanes and might find it difficult.
The cache is a magnetic and slightly smaller than a 35mm pot and there is parking nearby. It is also a very busy area so stealth is a must. Keep an eye on geokids and pets as the road is also busy. |The final coordinates are wheelchair friendly but will need help to retrieve cache.
You will need to do some maths and might need a calculator. Good Luck!
Here is the puzzle:
N 51° 2(EUNA+1-4000).(EUOC-EUOB-1) (EUYV-EUYU÷9) (EUXE-EUXC÷2) W 000° 3(XLEF-XLEE-3).(BYGE-BYGA+4)(VIIS-VIIOx2)(ZBKD-ZBJA)
