Large Cigar Shaped Object Chased By The Airforce In Chesterfield, New Hampshire

I was about 12 years old and visiting a neighbor up the hill. My sister was 11 y.o. The neighbor was 30 ish and her son was 19 years old.
 My sister and I were leaving to go home around 8:00 pm. We all walked outside, as we always did, and her son pointed to an object in the sky.
 We saw a large 'cigar shaped object' emitting light and hovering above us in the sky. It made no sound. We moved toward the back yard (which was a small field) in order to see it better.
 It started to decend right over us, like it saw us looking at it.  It got larger and larger but there was no way to really judge the size or how close it was, but it seemed bigger than the neighbor's house. It decended slowly and blocked out the stars in the sky. It felt like it was right on top of us.
 Then, without warning, the Object shot straight up in the sky at a speed that was astounding. It became the size of a Softball and bright white in the sky.  It stopped and angled right and zipped away so fast that you could only follow it for a few seconds. Then it was gone.
 A minute or so later, we heard and saw several 'Airforce Jets' from 'Pease Airforce Base' flying in the same direction the object retreated.
 The sound of the Jets made us realize that the object that we had just witnessed had no sound to it at all.
Witness indicates that date of incident is approximate.  PD
