Bushy: DC3 as firebombers - our current SEATS (in Victoria) carry minimum 2,500 litres of retardent - that's 2 and half tonnes (or a bit more, I'd guess the SG of retardent is greater than 1kg/litre). Some carry 3,200 litres. For interest, there's 12 SEATs on the Vict. DSE/ CFA contract for the 08/09 season, with more available through the 'call when needed' register.
