It sounds like anyone with a complaint will go for the easy target. last month I was one of the 'Lotto' Airships and we had numerous complaints from the public, all they had to do was ring up Camelot and voice their opinion.
Obviously with only 4 Airships in the country and all of them bright red with 'Lotto' on the side it was easy for us to be identified, although at some of the timings they gave there were no ships airbourne.
We fly low (1000-1500ft) like most helicopters, and this seems to be the magic height for anyone that feels they need some kind of compensation.
