Anything can be done on safety grounds.

Viz was down to less the 0.5km so totally unsafe. Also pilots were
unable to see to ground ahead and plan for safe out landing in the
event of not getting lift.

I am sure all pilots are disappointed, but none would have been happy
to continue on those conditions.
