Was at a hotel on the southern coast of Ireland, just enjoying the night air, when a light appeared about 30 degrees off the horizon, it shifted quickly to the left then got closer, I'd say about a mile or so then banked right and headed into the ocean. My friend thought that it might have droped behind the horizon but we both agreed that the horizon (Curve of the earth), was well above the point of entry.Much like above, except the thing seemed to have a "V" like shape almost like a delta wing, but white green. It was to dark at the point of impact to see if there was much spray coming off the ocean, but it must have done something. There was a strong wind that followed shortly afterward and we both felt it. Then nothing, now we are used to ocean breezes but this was much more and only lasted a second or two. I have never seened anything like this before.
