I will also take a look at the article that I have written on retardant and foam to see if the links still work and ascertain if it is time for updated articles.
In early 2009, Evergreen had a 747 tanker capable of dropping 20,000 gallons of retardant. My understanding is that the 747 tanker is no longer configured for aerial firefighting. I did have to delete one article on the 747 tanker because the article no long made sense after deleting outdated links. But I will leave the remaining articles up with an annotation that according to Bill Gabbert's May 2nd (2014) article on Fire Aviation it seems that Evergreen has declared bankruptcy.
