Boeing have a long history designing and manufacturing planes!
Many models have 'seven' in their name.....just forget about the sevens and use the information to locate the cache.
The cache is located at: - IC° AI.JEE', EDC° BJ.IBF'
There is not a lot of room for parking so be careful as the passing traffic may be going quite fast.
Please don’t draw attention to yourself or the cache in this highly public place and make sure that the cache remains well hidden!
Small 'plane' swaps only.
Enjoy the challenge!!!
