Arianespace has confirmed the loss of fight VV15 and the FalconEye1 satellite.
The loss occurred about 2 minutes into the flight. I think the other feed may still be active, but here is a replay.
The loss was evident in the control room even before the commentary had related any indication of something amiss.
The cause is yet to be determined but there the problems seemed to begin at the time of the time of separation of the first stage. I will of course update with more but not until later in the day as I will not be near a computer.
This just shows us that while these launches seem to be a routine event these days, it is very much not so.
