aerodynamics-defying object sighted

While walking down Main Street in Gibson after a music practice at the church, my friend and I looked up in the night sky at what appeared to be a jet plane at first glance.  However, we soon noticed that we heard no jet sound above us that would indicate that this was what it was. 
We commented on how strange this was and watched the object as it moved slowly over our heads to the east and over a hill (in the direction of the Elmira/Corning Airport)  To our amazement, when it reached the top of the hill, it just stopped, abruptly, in mid-air. 
As we were trying to figure out what kind of aircraft could possibly be capable of such a thing (and realizing that it was definitely not a jet plane) it took off at a speed that was both incredible and shocking.  We were stunned. 
We vowed never to tell anyone about it for fear of ridicule.  
I figure that I kept my silence for long enough and this report should be added to the host of others from every corner of the earth.
Witness indicates that the date of the incident is approximate.  PD
