Seems like valid questions to me. Were there any extenuating circumstances? Long story, but as an OPS SUP on a recent deployment, I found myself cancelling lines when the weather was "technically" legal. Things like lack of reliable weather reporting, lack of support at diverts, PR grounded for weather, zero Americans outside the wire, all lead to those decisions. We were never questioned by anyone in our chain of command...well anyone with wings on their chest and AF on their name tag.
