Thanks to everyone who came out to the soccer fields out in Enumclaw, WA on Saturday August 31st to watch the launch of our second High Altitude Balloon.  Weather was touch 'n' go, with Mt. Rainier in the background, to watch out balloon and payload sail away into the wild blue yonder on its two hour trip to over 91K feet and a landing 12 miles northeast of the City of Leavenworth, WA.
