Idiotic Airbus procedures probably contributed to the loss of SA in this case.
To have a checklist (before T/O checklist below the line) that cannot be commenced until after a line up/take-off clearance is received, is a human factors nightmare. This part of the checklist may only contain four items, but the checklist is being read at a critical time, often whilst copying a sometimes complex clearance, checking there is no-one on short final and manoeuvering onto the rwy.
I'll take the Boeing philosophy any day, where everthing is done before line up, leaving the crew to concentrate only on the necessary things at this critical time.
