We had a PZL Wilga in the tug line-up. Its an ungainly looking beast, but much quieter than the other tugs. That's due to the the huge, slow prop as much as to its large silencers. The other tugs were an assortment of Robins, Pawnees, a Rallye and, for the first two days, a Lycoming powered Chipmunk.
