    The flight profiles are not the same !!!

    I do it now with David H. Ransom "MAK2LINE" ... (I have Breez Keplerian orbital elements but not full and not for all mission stages).

    Some additional data up to the moment
    
    
    1)Parking orbit.

    10) End Breez retreat.
    Time after Liftoff = 9h42m05s
