Bright object with exceptional speed and navigational manuvers

Full Description and Details of Sighting.  Please provide as much detail as possible.  Your description can be as long as you wish, and can be longer than the size of the box.  The more detailed information that you can provide, the more useful it is for readers and for researchers.
I was with my family at the Waialae Drive In in the 1960s. It has been demolished and residential properties now use the land. The drive in was located where the present upscale Kahala Shopping Center now is across the way. The movie must have not been very good as I was instead gazing at the night sky which was cloudless and full of stars. However one was extra bright and caught my attention. Suddenly it zipped across the sky, then dived, and without decelerating, made a perfect right angle manuver, racing across at a lower horizontal level. Then suddenly, it zoomed off at an upwards angle and disappeared. At that moment I knew it was no airplane or helicopter because of the high rate of speed, wasn't a meteor as it ascended at the end, and that it was of intelligent navigation because of the right angle path trajectory. In "The UFO Book -Encyclopedia of the Extraterrestrial" by Jerome Clark, I note that there are 3 instances of the right angle manuver of UFOs (one on a radar screen). I submit here a fourth instance of this particular airborne manuver.

Appearance / Description of the Object(s) (What did the object look like?)  Please provide as much detail and information as possible.  You may wish to include shape, color, brightness, etc.
like a bright moving star erratically moving about the night skies

Size of object(s) -- if possible, please give estimates of both relative size and actual size: 
For relative size, if you held your arms stretched out in front of you, how far apart would your fingers or hands have to be to cover the UFO, for example "2 inches across"?  For actual size, what do you think was the actual size of the object (e.g. 30ft wide by 15ft tall).  If possible, please give both estimates.
Looking at the nightsky from within our automobile, it was like a larger bright star, maybe like the planet Venus when it is visible from our planet.

Estimated Distance & Altitude (height) of object(s):  If possible, please give estimates of how far away the object(s) was, and how high the object was.
Maybe 2000-3000 feet high?

Describe the Area / Surroundings : (Was it an urban or rural area? What was the surrounding area like? Also, were there any special sites or features near the area -- such as military bases, power plants, etc.?) Urban, clear night sky, about 70F, lot full of parked cars at a now defunct Drive In outdoor movie theater

Duration of Sighting (how long the sighting lasted)

Number of Witnesses (how many people, including yourself, saw the object/s)

Do you think your sighting can be explained as being any conventional man-made or natural object?  Natural objects include stars, planets (e.g. Venus), the moon, birds, and clouds.  Man-made objects include airplanes, satellites, blimps, and weather balloons.
not the rapid acceleration across the sky (3,000 mph?) or the perpendicular flight path at high speed
