I WAS A FLIGHT ATTENDANT WORKING A DELTAS FLIGHT FROM CINNINATTI, OHIO TO BUFFALO, NEW YORK

WE HAD STARTED OUR DESCENT INTO THE BUFFALO AREA, WHEN A GROUP OF JAPANESE TOURIST MOTIONED FOR ME TO COME AND LOOK OUT THE WINDOW ON THE LEFT SIDE OF THE AIRCRAFT, WHICH WAS A B-727. THE PASSENGERS DID NOT SPEAK ENGLISH, I LOOKED OUT A WINDOW AT THE OVERWING AREA CUPPING MY EYES FROM THE INTERIOR LIGHTS WHICH WERE ON DIM, WHAT I SAW WAS SEVERAL BARS WITH LIGHTS ON EACH END, WHICH SEEMED TO BE ROTATING VERY SLOWLY, ONE BEING AT A DISTANT DIMENSION THEN THE OTHER, PERIODICALLY, 
DISTANT LIGHTNING OVER CANADA WAS VISABLE, 
I NOTIFIED OTHER FLIGHT ATTENDANTS AND PRODCEEDED TO THE COCKPIT TO NOTIFY THE CAPTAIN, THEY DID NOT SEE ANYTHING OR OBSERVE ANYTHING ON RADAR, AS WE WERE IN OUR APPROACH TO BUFFALO, WE DESENDING OVER THE PA/ NY SHORE LINE OF LAKE ERIE, THEREFORE THE LAKE WAS ON OUR LEFT AND LAND ON THE RIGHT, 
AFTER DEPLANING IN  BUFFALO I PROCEEDED TO THE BAGGAGE AREA TO LOCATE THE PASSENGERS WHO WERE MET BY AN JAPANESE TOUR AGENT AND ASK TO VERIFY WHAT WE SAW, 
FOR SEVERAL YEARS NOW THIS INCIDENT HAS BOTHERED ME AND DECIDED NOW TO REPORT IT.
Date may be approximate, although the witness does not indicate that fact.  We have e-mailed the witness, hoping for clarification on this point.  PD
