Turbo S7, yes!
I remember Araracuara well! I used to have fun with the radar guys by flying as low as possible as long as possible to see when they could pick us up. If we were good we could scare the crap out of the guys on "visual patrol".
I also remember turning final there and as we passed over the river gorge losing about 15 knots and getting the stick shaker. In 30 degrees of bank, power back, descending, stick shaker rattling and a HUGE cliff staring you in the face is not where I wanted to be. Oh, yes, we had the American ambassador to Colombia riding in the jumpseat. Now let's execute that stall recovery procedure SMOOTHLY and CALMLY so that no one is the wiser.....
Luckily the wind came back before it got too ugly, and we salvaged the landing.
We had a great lunch (spaghetti!), and then pressed on to other needed places (Leticia, Iquitos, etc).
What a great landing!
