Josephine, that was amazing home-brew stuff.  Their maximum altitude was 108,000 ft and the highest picture that they post is from 92,000 ft.  In contrast, for the low-low price of only $200,000, you can now book on the Virgin Galactic suborbital spaceship and fly to 72,000 ft.  http://www.virgingalactic.com/booking/  Best use of a Walmart lunch pail (their instrument package housing) that I've ever heard of.  Hat's off to Mihir and Jonathan.  Thanks for giving us the head's up on your activities.  Clear Skies - Kurt
