2 objects dock -stay together 10 minutes then seperate in different directions -gain altitude until out of sight

Very Clear sky No sound Observed Very Bright round blueish white light moving from east to west-- appeared to be at very high altitude moved from east horizon to straight overhead in about 90 seconds-- Object stopped its westerly movement and just sat motionless for about 5 minutes straight overhead-- Then what appeared to be a smaller object came in from the north and docked (joined) with the bigger object--the two objects stayed together for 10 minutes--Then smaller object broke away from larger object and went to east south a short distance and appeared to gain in altitude until it went out of sight--Larger object stayed stationary 2 more minutes and then moved back to the east a short distance and  appeared to gain altitude until it was out of sight-- Both objects had smooth movement and were under control-- Larger object stayed in same exact same spot when not moving and did not drift at all-  The biggest bright object was about the same brightness as the -North Star- except is looked to be about twice the size-- The smaller object appeared to be one quater the size of larger object but was the same brightness--neather object changed in brightness and had no flashing navigation lights ect.
 El Paso at the time had 2 military bases-Air Force-SAC and Army base missles-- so I have seen lots of missles and aircraft-ballons ect-- These objects did not look like anything I have wittnessed before or scence--In 1967 the Us was still in the Gemini space program and were still trying to dock space craft--  Threw the years I have not learned of any military program that would explain what I observed--Jay--
