Here’s truth to the famous Goose incident. My father knows the parties involved. The whole story can be found on Alexis Parks site. Same pilot was at the controls of this famous incident.

On the first day, the Goose took off from the airport. The plan was to fly
out to Cabo Velas, return along Playa Grande and land in the bay near
Tamarindo estuary, where the crew would board, then to take off on their
adventures.
The camera crew set up on Tamarindo Beach, ready to shoot the approach and landing for the movie. But instead of flying from Cabo Velas, approaching Tamarindo from the west along the Playa Grande coastline, the big Grumman twin came roaring down the river from the north, putting on a show for the camera. On board were the pilot, “Hoot” Gibson, and local resident and California board shaper, the late Mike “Doc” Diffenderfer.
Approaching Tamarindo, the pilot started a right turn to follow the
estuary, but his height was insufficient. Presumably he suddenly became
aware of the power lines which cross the river at that point, and was
forced to fly below them. The right pontoon caught the water, and jerked
the aircraft to the right. Overcorrecting, the pilot put the left float
into the water, and the aircraft swerved to that side.
Gibson applied full take-off power to get the aircraft back into the air,
but it careered from the river onto the beach, where it ground-looped and
came to a stop. The whole incident was filmed, and eventually became part of the movie.
“At this point,” said August, “we saw fuel spraying from the aircraft onto
the sand, and there was a distinct danger of a fire or explosion. As we
approached the 'plane, the doors opened and Hoot and Doc jumped out,
fortunately both unhurt. From a nearby beach house, a resident came
running, carrying a big club and shouting at the pilot that he was in a
national park, and polluting the beach. We managed to calm him down, and the incident ended at that point.”
