    These TL show that there's 'only' 530 m/s missing at apogee, what a manoeuvring
    payload could compensate, but it also represents the loss of many years of its life.
    (~50 m/s/year for geosationary stabilization)
    
    I am probably wrong but I feel the flames were very orange for a LH-LO mix...
    or my video player distorted the colorimetry ! :-)
    
    No doubt, all gathered data will lead to full success soon.
