Cigar shaped UFO over north Houston,, before the building of IAH.

In the summer of 1963, my mother was hanging clothes on the clothes line in our back yard. She called out to us kids to look up in the north sky at the strange gray cigar shaped object which was hovering. It was very high, I would now estimate that it was 75 to 90 degrees high, and had no contrail, no sign of movement.  
It's hard to estimate how long it was, as it was very high. It was not a blimp or a weather balloon either!!  
We lived very close to H&H Guest Ranch, which had gliders and skyjumping on weekends, but this was a weekday and that was NO glider!  
The object held our attention for a few minutes, but being kids, we went off to play and about five minutes later looked up to see it was totally gone. 
This was my first sighting of a UFO.  My second is also documented here.. 05/01/69
Witness indicates that the date of the incident is approximate.  PD
