Coulson has been working on both of their Martin Mars aircraft, the Hawaii Mars and the Philippine Mars. At one point this week both of them were floating in Sproat Lake adjacent to the Coulson facility for the flying boats.
The company has repainted the Philipine Mars. It no longer has the red and white air tanker colors and now resembles its original military paint scheme. Coulson is still pursuing a plan to sell or trade the aircraft.
The Hawaii Mars is scheduled to make its first trip to the Oshkosh air show July 25 through July 30.
