Notso:
"tech log pages still unpulled, signed loadsheet still onboard, cargo manifest documents on/off" - does your checklist not require the checking of ships papers in the pre-start checks? And if so (as it should), why would it not have been an open item if said papers were not completed? And if it were an open item, why would the push be commenced while the item was still open? And would any other items have been overlooked?
Persumably also the beacon was switched off to allow personnel to approach the aircraft...
Pedantic? I dont think so. The consequences of skipping checks are obvious to all.
