I think guys that you have focused to much on the PAN PAN fuel story and forgot the basics on fuel planning.
Met +- 1 hour should be aboved minima on destination and alternate. For alternate planning you have to take in consideration 1 step above, that its for CATII we take CATI and so. So why the guy decide to overshoot at 300ft on alternate? knowing 500mRVR you overshoot at your IAF and go for next one. I think the guys just tried to get to the nearest one fast and forgot this, now someone can f..k them cause they did it wrong, the rest of the PAN PAN story is out of the question.
