Rumour in our Ops Room tonight is that this will turn out to be another example of the perils of ' taking it on the roll ' in a rush to beat the inbound traffic.
Easily done, especially at Nice, to lose situational awareness when you're in a rush - almost did it myself about 20 years ago in Nice until we saw a set of main lights suddenly turn towards us just as we were thought we were ready to launch.
Never took it 'on-the-roll ' again after that night !
