| UFO Mystery on a 707 Proving Flight
After return of the first leased 707 from National Airlines, before operations could commence on Latin American Division routes, proving flights with FAA personnel on board had to be performed.
One such proving flight was scheduled from San Juan, Puerto Rico, to New York City. My boss, Capt. Dick Vinyl, was the pilot and I was assigned as an observer and sat
A small light momentarily lit up in the center of the pilots window panel. It repeated itself except this time a few inches away from its first appearance. After several of these intermittent flashings in different locations, Capt. Vinyl took notice and alerted the crew. The flashing persisted and we all began to offer opinions as to what it was.
The on/off light persisted for most of the remainder of the 4 hour flight but disappeared at the beginning of our descent into Kennedy.
A short time later, the supervisor came over and explained that he had an answer to our mystery. The windshield panels consist of two layers of glass with an airspace between and a lightning bug had somehow entered the airspace and with its ability to exude a light every few seconds was the cause of the intermittent light we had observed for several hours during the flight.
A true story.
