Witness Account

Around 6:13pm saw a small plane flying by in the distance over the Gulf of Mexico. at the time of sighting I was about 1 1/2 miles from the Gulf a round object appeared as plane was passing by and it caught my attention at first I thought I was a incoming plane but soon afterwards another object appeared very close to the first object about 30 seconds later a third round object appeared about 200 feet below the first two. I would say these objects were about 4,000 feet up. Me and my 10 year old son watch the objects for about 4 minutes before they disappeared. Tried to take video but they were to for away for my cell phone.
