The "Global Supertanker" has been cleared to help battle the wildfires burning in California.
The U.S. Forest Service says the delays were caused by tests performed on the tanking system that needed adjustment to ensure proper payload delivery of fire retardant.
With more than 11 active wildfires currently burning in California, the converted 7-47 should prove to be a valuable tool.
"We can lay lines down that are extremely long unbroken lines that might take other tankers five to seven drops to do... we are accredited with actually saving lives and saving structures and buildings, and saving towns," Cpt. Tom Parsons with Global Supertanker Services.
The Forest Service is only allowing the tanker to fill to 5,000 gallons.
The plane can carry four times that amount.
There are five active fires burning in Colorado as of July 25.
