The 7,200-gallon Martin Mars air tanker is on contract for the province of British Columbia this summer. The U.S. Forest Service contracted for the huge aircraft for the last two years, having it based at Lake Elsinore in southern California in the late summers of 2008 and 2009, but as far as we know, they have declined to sign it up this year. The B.C. contract is from June 1 through August 31 and guarantees 45 days of work for the aircraft.
