Swissport have 3 rigs and Airline Services (the company that caused all the delays today) have around 10 iirc. I believe Swissport even de-iced a few aircraft for Airline Services today.
Do we know how many of those rigs were serviceable and being used at any one time? In other words, were there enough staff to operate all that were available?
Quoting MAN777:
"All those months of good
PR and good feeling for MAGs future dashed in an instant by a bit of snow. (no excuses, it was forecast)"
Certainly bad
PR for the airport, whether justified or not, but the forecast (TAFS) was not as severe as the weather turned out. As I recall, the likelihood was rain and snow (sleet) with only a 30% probability of temporarily c1200m in snow. More significant snow was only expected at higher levels. In the event, the snow at MAN was more intense at times with only 600m met vis. and was more persistent. (If it's the met office that provides the forecasts, they've also failed to predict dense fog on a few occasions in recent years).
Nevertheless, the risk of disruption was evidently there and one would have hoped proper planning by the various parties would be in place. That said, the airfield ops. teams must have done an excellent job to keep the runway open.
