I can't remember if this was ever posted... Seems like something someone here would know about:

I lived in Sitka, Alaska when this took place. It had people concerned.... for a few short minutes.
Then, everyone from the local bush pilots to the FAA.... said, hey.... there is only one guy here who owns and operates a helicopter. So, they went to visit the Jetranger owner. He fessed up quick and I don't remember any serious action taken by the FAA other than a hand slap. Possibly a minimal fine to discourage others. (what he used was old tires to create the fire and smoke)
What is interesting from a backcountry fixed wing pilots perspective though... is Frank Taylor. I taught him to fly the Beaver on floats. He was pretty good but took too many chances with weather. Anyway, one day he was seen in his cub... landing upslope on Mt. E..... to the right side of where you see the smoke rising. The angle was amazing. He would whip around in a 180 before he lost momentum and race back down the slope to take off. I got invited to try it but declined. The one thing we did on occasion was land the Beavers and the 185's on straight floats on the glaciers up above Sitka. That was fun and pretty straight forward. You drag the snow first to lay down tracks.... them come around and land. The angle at touchdown is somewhat startling though... very flat and nose low... not like water at all.
Sadly, Frank met his end on the south end of the island one day taking my grocery run out to a logging camp for me so I could get a day off. He pushed it too low and never came back. Great guy... and his wife took a long time to recover.
That photo sure brings back memories.... thanks Zane. (trying to think of a good sound track to go with the pic )
