2 ufos seen over mt pinos, people in sleeping bags gone in morning, airline pilots on ground see objects also

An earlier sighting in the early 50’s more than likely 1951 my family went camping on mt pinos in the los padres national forest. They would go out on the road past the ski parking area where only a few hunters and campers went.  There would usually be only 6 to 8 campsites occupied.  
They got there after 10 pm and noticed 40-50 people out in sleeping bags without tents. This is at 8600 feet so it gets cold.   Mom told me they set up their tent and went to sleep. My brother 3 or 4 at the time slept in the car with my mom’s aunt (grantee). 
About 2 am my mom told me she heard a lot of people walking around and thought "that’s a lot of people going to the bathroom" in the morning the tented normal campers were there but all the people in sleeping bags were gone.  She ask her aunt how she had slept. 
Her aunt responded that she felt really safe last night as there were 2 helicopters hovering overhead for several hours and they were shining lights down.  They also had multicolored lights showing and made no noise.  
Several days later my dad who worked in Hollywood was eating lunch and 2 airline pilots who knew him ask him if he had gone camping on Mount Pinos on Saturday night.   They had some acres in alfalfa up near Quail Lake and were out irrigating that night. 
They had seen 2 UFO’s fly in from the east and then a few hours later fly back out to the east. These were army air corps bomber pilots that were now working for a major airline and could not ask anybody in the industry or they would have their pilot tickets pulled.
