Factual error: When Mouth flattens the tires on Brand's bike, all he does to let the air out is take the valve caps off. There's actually a valve in the valve stem that needs to be depressed to let the air out. The cap is just there to keep dirt out of the valve, simply taking it off wouldn't let the air out.
Factual error: Two of the huge rocks which plummet from the roof of the cave hit the water and then bob to the surface again. Pumice is the only rock which floats on water, but this rock is white and pumice is grey, and pumice is too light and porous to form cave walls anyway.
Factual error: As Stef is stepping down the fireplace, you can see that her Nike swooshes are drawn on her shoes. Nike never made shoes like that. Converse made them for a couple years in the 80s. (00:46:00)
Factual error: The Goonies are from Astoria, but they ride their bikes to Cannon Beach; this is where the Lighthouse Lounge is, a distance of over 30 miles. When they descend in the tunnels below the lounge, they supposedly go under Astoria Country Club and Moss Garden. This would be impossible.
Factual error: When the Fratellis are getting away from the police at the beginning of the movie they go to the beach to blend in with the other 4x4s. Mama Fratelli tells Francis to put their Jeep into 4 wheel drive but you can see him put it into 4 wheel low. It's impossible to drive as fast as they did on the beach in 4 wheel low.
Factual error: There are a few problems with the suction cup that Data shot onto the metal drum. First off, suction cups don't stick to curved surfaces. Second, dirt and grime, which the drum obviously had, would not allow a suction cup to stick. In any case, it shouldn't have stuck.
Factual error: When the Fratellis break Jake out of jail, Francis shoots a trail of gasoline on the ground with his pistol, which lights it. In reality, this wouldn't happen, more than likely the bullet would bounce of the ground or embed itself, but not cause any sparks (if it caused any, wouldn't be long or hot enough to ignite) to light the gas.
Factual error: When the Goonies go below deck on the pirate ship, we can see water is leaking through the hatches on deck. In reality, the ship would've filled up with water and sunk in a matter of weeks, if not days, so there's no way on Earth that it lasted as long as portrayed in the film.
Chosen answer: Well, his ship is hidden in America where the people spoke english, so perhaps it was done for the benefit of those who were most likely to find the map. Must have been his idea of a joke.Actually though, I'm betting it was the result of the filmmakers not thinking that through.
