You're a new Grumman Goose pilot in the Amazon region of southeastern Peru. It's not glamorous work, but there's always the possibility of some adventure along the way.
On this afternoon's flight you'll fly north from Quincemil Airport (SPIL) to an archaeological base camp on a lake to pick up supplies. Then you'll fly the supplies northwest to a remote village on another lake. It's been raining for days, so you'll have to fly low to stay out of the clouds.
The mission begins on the runway at Quincemil, with the engines running.
