For more details on that experiment read Secrets of Antigravity Propulsion by Paul LaViolette, Ph.D.
He goes into all the math behind electrogravitics, Tesla, T. Townsend Brown, who if I remember correctly worked on the Philadelphia experiment and it haunted him the rest of his days.
That's just a NAVAID for the IFR approach/ departure for Cape Canaveral. Pilots use this particular approach if they go 'missed approach'. Which means they aborted the landing due to weather being below minimums. COMET is a location over the water out of the traffic pattern where they can hold to see if weather will clear for another approach.
