A black disc/oval shaped object was seen going directly up.

A black oval/disc shaped object was seen going straight up approximately 4-6 miles away from where we were standing.  We were mezmerized watching it, when from the west, a large plane/jet suddenly made a 180 & headed back in the direction from which it came. 
Then we realized it was becoming larger, actually coming closer to us.  We were both on bicycles & quickly rode them to our individual homes, frightened that the inhabitants would find us & take us up into their 'craft'...as  this was at a time when people reported being taken & probed by aliens.  Cimmaron Strip was on the television as i sat there in fear.  The only person who believed we were speaking the truth re what we saw was my father.  All others we told of our experience laughed & made a joke of our ordeal.  
Neither of us were ever sure what it was that we saw that day.
Witness indicates that the date is approximate.  PD
