This is from the weather sketchbook. The next painting is basically the same image but on better paper. (Arches) The last two pieces are watercolor, 7x7" on Arches. The bigger airplane is actually a converted jumbo jet (DC-10 tanker) which can drop 12,000 gallons in a single load. In this case, it's dropping fire retardant. It has finally rained, so enough of the fire images. There's more fire fighting in my October 2006 file.
