Rich Coutu, of the Port of Seattle airfield-maintenance crew, uses a pressure-washing tool to remove rubber left by the tires of landing planes from the center runway at Seattle-Tacoma International Airport recently. An Alaska 737 is seen taking off in the distance. Removing the rubber, using pressure of 40,000 pounds per square inch, gives planes more traction when landing. The maintenance is performed three to four times each year. The runway closures do not affect flight schedules.
