Thank you for the unitedcargo website. That what the CSA must have been quoting when she said it was all weather related. It does indeed cite "operations" as the reason for cancellation both on the mechnical failure day as well as the weather days. What a load of crock. We had a blow-by-blow description from the captain over the PA as they turned the plane power on, off, on again, got assistance via tech crew in another airport, etc, then finally turned around and deplaned.
