So did one solitary birdman work all hours that the airfield, sorry I mean airport, was open, i.e. circa 16 hours a day, 7 days a week with no public holiday nor annual leave entitlement?
What happened when he wasn't there, did the AFS or ATC covered BCU duties, did birdstrikes only occur when the birdman was off duty and what did he do when he was there?
One could drive around the entire airfield in 10 minutes, I wouldn't believe the size of the field, or the number of movements, would justify a dedicated BCU unit.
