Tanker 12, the BAe-146 air tanker working the Sunshine Fire near Boulder, Colorado on March 19, was dropping retardant about every 35 minutes, according to Rob McClure of the CBS TV station in Denver.

After a million acres burned in Kansas and Oklahoma on March 6 and 7, the National Interagency Fire Center mobilized three large air tankers on March 10, a little earlier than usual, sending Tanker 12 to the Jeffco Air Tanker base at Rocky Mountain Metropolitan Airport and two others to the OK/KS area.
It turned out that Jeffco was only 12 miles southwest of where the Sunshine Fire started on March 19 near Boulder, Colorado. Rob McClure of CBS4 in Denver timed the interval between drops made by the BAe-146, determining it to be about 35 minutes.
From the air tanker base the pilots could probably see the fire soon after it started. If they took off from runway 30R they would be heading straight at the fire.
In addition to Tanker 12, four helicopters and Colorado’s Multi-mission aircraft were working the incident.
Three National Guard helicopters were made available by a verbal executive order by Colorado Governor John Hickenlooper hours after the fire started. The aircraft, from Buckley Air Force Base, included two UH-60 Black Hawk helicopters, one CH-47 Chinook helicopter, as well as a refueling truck.
Firefighters limited the wildland/urban interface fire to about 74 acres according to the Boulder Office of Emergency Management. We were not there but this appears to have been a pretty aggressive initial attack, an aspect of firefighting along the Front Range that has improved in the last couple of years.
