All ? PBH-10, our test flight, was successful and we plan to launch  
our first mission at 1800 EDT (2200 UTC) 21 April 2010! Be sure to  
check our Twitter feed <http://www.twitter.com/PBH3> to for the latest  
updates.

NOTE: While we plan to launch at 1800 EDT, actual launch time may vary  
depending on optimum ground conditions encountered in real time at the  
launch site. If conditions force us to postpone tonight's launch, our  
team is on standby to launch at 0600 EDT (1000 UTC) and 1800 EDT (2200  
UTC) each day until a successful launch occurs.

Please see below for important information about our first mission  
which consists of two balloons that will be launched directly after
