'Big spray can'

The same kind of airplane that has transported U.S. presidents, rock bands and countless passengers all over the world will soon have another claim to fame.

A modified 747-400 freighter is about join the firefighting ranks. With the capacity to carry nearly 20,000 gallons of water, fire retardant, gel or foam, it’s the first 747-400 to be used for that purpose.

This particular airplane rolled out of our Everett factory in November 1991 as a passenger jet, and later became a Boeing-converted freighter. It was in Seattle this week after a few days of water-drop testing near Moses Lake.

Pending certification by the FAA next month, it will be the only 747 tackling blazes around the world. Because of its size and its speed, the 747 can reach almost anywhere in North America within 4 and a half hours. And it can fly anywhere in the world in 20 hours with just a single fuel stop.

“It’s basically a big spray can,” said Bob Soelberg, senior vice president and general manager of Global SuperTankers of Colorado Springs, Colo., which operates the airplane. “Its wings are bigger and its engine more powerful than anything else out there fighting fires today.”

The airplane is equipped with 10 tanks, each with identical systems that can operate independent of one another. The airplane can deliver single or multiple drops of water or fire retardant that can be released at variable rates, producing a tailored response for various fires.

Just mind blowing! Awesome video and such an extended time for water release.

Boeing is incredible.

Base it in San Bernardino Intl, it is so vital for the firestormes that we have in SoCal.

Bill Nation (Kerrville, Texas):

So, when my grill flares up, I know who to call. Good to know.

NickSJ (Orcas, WA):

According to another article, the spray equipment in this 747 was transferred from a 747-100 once owned by bankrupt Evergreen International. For reason unknown to me, the previous 747 tanker was rarely used. Anyone know why?

Robert merrill (Sarasota,fl):

Years ago Evergreen int. Airline had a 747-200 tanker,no idea what happen to the a/c
