Did you need all 4 reheats to go from 0.95 - 1.7 ?
If you got to 1.3 and then one or more failed could you continue (albeit with slower acceleration ?)
I presume if you were unable to get the things lit at 0.95 you just turned round and went home again ? The procedure would take around 90 mins so would you need to burn off fuel or already be at acceptable landing weight by that time ?
Also, once when aboard at about 50K-55K feet the aircraft rolled I would estimate 3 degrees to the left and then came back level again almost immediately. I knew this was a glitch but no one else noticed. An announcement was made of a minor problem about 2 mins later and that was that ?
What might have cause such an event (I would guess an airflow issue with intake or engine ?)
