If they were holding at CCK, which would make sense, there is two limitations on the holding pattern.
1. 5000', 1 minute min or D14.0 whichever happens first with a max 170 Kts airspeed
2. 6000', 1 minute Max IAS 210 Kts.
Is there a company policy that states not to apply MBZ procedures if the Tower is closed? Or were they holding due to fog.
Two scenarios here.
A. They either misread the chart and didn't put in the paperwork!! or
B. Bull
