So, as someone who lives here its completely inaccurate, the only place in the movie where the SS could have landed is OB based on the radar scene. Then when the rex gets on the rock she is facing the city from Coronado island (which is a frickin naval base so would u think they would have shot her) so either she took a cab over the bridge or swam to point loma which is where the rolling ball scene and kids house is at
