Please put any additional remarks, sketches, drawings, etc. below:
  Witnessed fireball at approximately 9:48 pm EDT (+/- 2 mins).  Appeared in 
the East or Southeast with a radiant in the WSW; appeared to be rising up 
from the
WSW as if it were moving upward away from the surface of the Earth.  trail
appeared to rise up toward lower (Eastern) arm of  the cross in Cygnus from 
the
WSW.  Trail was foreshortened and appeared to curve around before exploding 
a
few degrees (5 degrees?) below and south of the arm of the cross in Cygnus. 
The trail was very foreshortened and it appeared to spiral slowly and 
tightly away
from the observer.  From the observation location it appeared to explode 
approximately due east of the
observer, just below a passing airplane, approximately one mile east of the
observer and heading south at a flight level of perhaps 10,000 feet.  (This
flight path was subsequently used by other aircraft over the next 20-30
minutes.) My initial thought was that this may have been a missile strike
attempt on the airplane.  However, the radiant of the fireball, date, and
description appears also to be consistent with alpha Capricornids.
