How to Fight the California Wildfires With a Boeing 747 Jumbo Jet

The largest and most destructive fire burning in California continues to grow, consuming dry brush as it races not just through but across the canyons north of Los Angeles. Strong winds and dry conditions mean flames can leap large distances, prompting thousands to evacuate their homes. The Thomas Fire has now spread from
Ventura County into Santa Barbara County, burning up 230,000 acres—an area larger than New York City and Boston combined. The out of control blaze is on track to become one of the largest in California history.

So firefighters are using the largest tools they have to tackle it, including one that's more than 200 feet long, and does its work from just 200 feet above the ground.

“We avoid flying through smoke at all costs, but you can smell the fire 200 miles out, even at 20,000 feet,” says Marcos Valdez, one of the pilots of the Global Supertanker, a
 Boeing 747 modified to fight the fiercest of fires. The jumbo jet can drop 19,200 gallons of fire retardant liquid per trip, nearly double the  capacity of the next largest air tanker, a McDonnell Douglas DC-10. Fully stocked, the plane weighs in at 660,000 pounds, comfortably under its 870,000-pound max takeoff weight.

Step inside (which you can do in the interactive 3-D model below) and you'll see that the upper floor looks pretty normal, with the cockpit and a few seats. Head down
the stairs to the main floor, though, and you'll see the key changes its owner, Global Supertanker LLC, made when it converted the Japan Airlines passenger plane to a firefighter in 2016: In what looks like the interior of a submarine, you'll find eight cylindrical white tanks in two rows.
