Slow moving large red spherical object moving in a upward direction over the town. The object then split into two seperate objects and each one went a different direction at a high rate of speed.

In the spring of 1968, I was standing in my front yard with a few of my relatives. I was looking to the south over the town of Delta, CO (western Colorado) and saw a very large object that seemed to be moving away from me and slowly rising. The object was spherical and bright red, it also seemed to have a glow about it. After watching this object for approx. 15-20 seconds it suddenly split into two seperate objects.  Both objects took off at a very high rate of speed, with one moving in a horizontal western direction and the other moving in an upward southeast direction.  They both were moving at such a great speed that they were out of vision in just a few seconds. This happened over thirty years ago and is not a fantastic sighting, but I am curious if there is anybody out there who might have been in the area during this time and witnessed anything like this.
Date is approximate.  PD
