I learned to fly at Fullerton in the mid-late 1960s. Airspace in the L.A. Basin then was a free-for-all; you could go wherever you wanted NORDO except into the "Airport Traffic Areas" (what we call Class D now) of towered airports, and the few military restricted areas. The first "Terminal Control Area" (now "Class B") appeared in September 1971. Even when President Nixon was in residence at the Western White House in San Clemente, Prohibited Area P-25 was only a one-mile radius and up to 4,000' MSL.
Smog was worse then than it is now. Many a day during my training we would stare through burning, watering eyes at Fullerton Tower's rotating beacon, which indicated visibility was still under three miles. As soon as the beacon went off (the tower guys were very optimistic on their visibility estimates -- they were bored, too) we would fire up.
Fullerton was busy then. More than once during solo pattern work I was "number 10" on the downwind to the single 3200'x60' runway, and told to extend downwind to St. Jude's Hospital. St. Jude's is three miles from the airport. Fullerton has never been an easy airport to spot from the air on a clear day. But turning final for runway 24, into the setting sun, when visibility was "three miles" :wink2:, it was impossible. This was before the runway 24 localizer at FUL, too. Turning final was more a matter of faith and local knowledge than being able to see the airport.
Oh, and pattern altitude was only 800' MSL then. One would be well advised to remember the 760-foot-tall KFI radio tower two miles northwest of the airport, not far from where one would normally make the turn from crosswind to downwind.
We had no shortage of places to go within an hour's round trip in a Cessna 150 ... museums at Chino and Orange County; sporty Meadowlark with its 1750' runway, San Juan Capistrano -- even Catalina.
It was a great place to learn to fly.
