Time: Wed June 14 2023 1030 AM Location: Approach to JFK Delta flight 5294 RDU to JFK Around 1030 AM roughly 10-15 mins to touchdown. We could see the shores/beaches of i'm guessing what was southern Long Island. We were sitting about 4 rows ahead or so of the left wing of plane. Both myself and my 14 year old son saw a fairly large (est 10ft in diameter) clear bubble with a reflective red bypyramid inside (like 2 pyramids connected at the bases). Guessing it was about 30yds out past the end...
