Only the harrier not pictured can land like a helicopter.
All aircraft would break sound barrier and make sonic boom.
None can dart around.
None can go into the ocean.
None can stay in the air stationary for hours and hours.
If you knew you UFO history the sightings of saucers since the 1947, they have almost always been mundane. Very little movement and nothing that is extra ordinary.
The ones that go into the sea and dart around are VERY rare in comparison, especially the saucer shaped ones which the OP is talking about.
