Thing is at the likes St Petes and Helsinki BA are probably chucking a handful of airframes a day into the hands of an experienced/practiced set of driving teams.....at LHR BA would be throwing several hundred airframe a day in the direction of teams who see proper snowfall once or twice a winter, if that. I’m sure if enough money was thrown at the driving we wouldn’t see the sort of problems we had yesterday....but someone, somewhere has made a decision (cost v benefit).....
