“That’s why they flew straight into the bad weather that other aircraft were flying around.”
Your words. That states the crew deliberately flew into the storm due to a lack of fuel. There is nothing “technical” in that wording. Stop while you’re ahead.
The possibility that they would have to stop and refuel (something airline bosses don't like) gave them the motivation to do what they did.
The Speigel article reports that data from the FDR indicates the plane attempted to steer around the storms.
“But the flight path recorded by the black box reportedly shows that the crew had been trying to find the safest possible path through the storm front. They initially appear to have succeeded as the flight data doesn’t contain any evidence of more severe turbulence.”
