Introduction to EUSO-BALLOON 5th progress Meeting LAL, April 19th 2012

Introduction of theEUSO-BALLOON 9th Progress MeetingNaples, November the 9th, 2012 Guillaume Prvt, Sylvie Dagoret and Peter von Ballmoos1EUSO-BALLOON, 9th progress Meeting 2012first flight in spring 2014 from Timmins (4834' N, 8122' W)

CNES campaign starts March 1st 2014

=> EUSO BALLOON is to be flight-ready in Timmins by end of february

flight scenarios have been elaborated by Jean Evrard for the december flight review

=> we can make it, but must stay on tight schedule
