I have been informed:
The trans-atlantic balloon attempt, PBH-15, has been postponed until next week due to unfavorable flight predictions and some last minute testing issues.
They will now be attempting to launch PBH-15 sometime next week (4/27-4/29). Latest info can always be found on Twitter (@PBH5) or by contacting <triebwasser at gmail.com>
Thanks for the help and hope to hear from you next week.
