In the 1960's I saw them flying over my house on a regular basis. I lived about 1/2 between Travis AFB and the Pacific Ocean. A very distinctive sound from the 4 turboprops. Strange that they always seemed to fly about 10K-15K feet above ground level, never higher. Maybe just training flights.
Imagine they would still be in climb or let down until well offshore, not a huge rate of climb. Also wonder if there was some effort to limit pressure cycles on the hull, thus keeping at lower altitudes for circuit work? Cracks were a known issue even before the catastrophic failure in 1970.
