Flagging comment from Andy Jorgensen
People, do your research from Coulson Flying tankers re fire suppressant “Once airborne, the foam concentrate is injected into the water load (normally, 30 US gallons of concentrate into the 7,200 US gallon water load) where it is dispersed and remains inert until the load is dropped. Once dropped, the tumbling action causes expansion which converts the water load into a foam load. This process is repeated for each drop. In other words, this vital team work is carried out, on average, every 15 minutes per aircraft. For a Gel drop , the concentrate is injected during the scooping process to allow even mixing.” It is out of work because it is expensive to operate and the company needs a season retainer to make it worth their while , it is not retired because it is 70 years old, it does not only use water, it is expensive , not agile , and needs big lakes to suck water from. Get the fact before freaking out, however the fire center is in charge of operations and would scream a storm if they were told NOT to use resources for political reasons .
