Went to my local town beach which is right on buzzards bay with a friend. it was a very clear beautiful day as you can see clear across the bay which is more than a mile to the other side which is cape cod. as i was scanning the shoreline across the bay just looking at the sites i noticed a huge blimp like object gray with no colors just hovering in the distance over the land it appeared to be gigantic compared to houses on the ground beneath it almost could have been a mile long it's slowly move back and forth for a couple minutes as i was still trying to figure out if i was watching some gigantic blimp or something and then it began to get what looks like smaller but then i realized it was just turning left about 90 degrees facing down the ocean on the other side and at that moment i realized it wasn't a giant flying saucer but a giant cigar shaped aircraft of some sort and then it's sort of got smaller as it went away from us towards the atlantic ocean and it got smaller quite fast so almost represent that it was going a pretty good clip. there was no other witnesses on the beach that day and after the sighting we we're trying to figure out what exactly we had seen. looks like something out of independence day and i was quite blown away to have seen something like that in my lifetime. we literally left after the incident and i have been trying to find out if there was any kind of air show that day because there is a otis air force base right in that vicinity or some kind of blimp thing going on but every thing that i look into says nothing and with no other witnesses and it's pretty astonishing to me how no one could have seen this gigantic object just over their heads. and that's probably why it had that hazy look to it because it was using some kind of active camouflage. i didn't know what to do so i didn't report it for a while but i feel like people need to know what i've seen and i can't believe what i have seen.
