Greetings Pilots and Passengers!

It has been recently discovered that the Ancient Mayans used crystals including Quartz and Zeolite to purify water as part of an advanced filtration system. This is now believed to be the oldest filtration system to be used in the Western hemisphere around 2,700 years ago.

It goes to show that there is a lot we don’t know about our history and that back then we seemed to know a lot more about the world than we do today!

Fly High, Fear Less.
