Lead Balloon, if they walked up, found an Aircraft devoid of fuel in the tanks with video evidence of it taxiing out with Low Fuel Lights on and being able to see that the fuel at the start of the day and fuel uplifted throughout didn't allow for the flight to be done safely, do you think they'd waste much more time looking through for more Maintenance defects? Not unless they've got an axe to grind I'd say. The fact that they specifically singled out the "Fuel Quantity Indication Systems" and not just the "aircraft maintenance requirements and records" says to me there's a bit more to it than just someone taking off without enough fuel and hoping for the best but that's just my opinion based on what I can see so far presented.
