We Were Holding Station Off North Sentinel When The Sea Went Flat

I'm going to set this down the way I'd write an incident report, because that's the only way I know how to write anything. If I try to make it sound like a story I'll start rounding things off, and I've spent nineteen years being paid not to round things off.

I turned fifty in January. I work on cable ships — installation and repair, mostly repair these days. I won't name the vessel or the operator, because I signed documents saying I wouldn't and I'd like to keep working. I'll say it's a DP2 repair ship, a bit under 130 metres, and that in the last week of March this year we were working a fault on a system in the Andaman Sea. That's as specific as I'm willing to be about the job.

What I will be specific about is where we were sitting, because it matters.

We were off the north-east corner of North Sentinel Island. Seven and a half nautical miles off it, holding station, in about ninety metres of water. Outside the exclusion zone, which is five. We had our permissions in order and an Indian Coast Guard vessel had come out and looked us over two days before and gone away satisfied. I mention this because the first thing anybody says when they hear North Sentinel is "you're not supposed to go there," and no, you're not, and we didn't. Nobody on that ship had the slightest interest in going near it. The people who live there have been clear for about sixty thousand years that they want to be left alone, and the general feeling on board was that they've earned it.

But you do look at it. You can't not. It sits there on the horizon as a low dark line with a bit of green on top, and at night it is completely black. No lights. Not one. In a part of the world where every scrap of land has a phone mast and a generator and somebody's television on, that island is a hole in the map. Our second mate used to say it looked like a bit of sea that had gone hard. You'd catch people on the bridge wing just looking at it, the way you'd look at a fire.

The job we were on was slow. We'd done a grapnel run, cut the cable, recovered the eastern end and buoyed it off, and we were waiting on first light and a bit of the swell dropping to go and get the other one. That means a night of nothing. The ship holds herself on the thrusters, the generators run, and everyone who isn't on watch is asleep or pretending to be. I'm not deck crew — I'm on the engineering side — but I keep bad hours and I've never been able to sleep through the last part of a night, so I'd got in the habit of going up to the bridge with a coffee about four and standing out on the wing until the sky started going.

That morning I make it about a quarter to five. The sea was as flat as I've seen it out there. There was a long low swell coming up from the south-west that you could feel in your knees but couldn't really see, and the surface was that oily, dented look you get in the pre-monsoon when there's no wind at all. The sky in the east had gone from black to a sort of dirty grey, the way it does about forty minutes before the sun. You could just about make out the island as a shape rather than an absence.

I saw the light with the naked eye, and my first thought was a fishing boat, and my second thought was that there shouldn't be one there.

It was low. Not on the horizon — above it, but not far above, and off to the left of the island's northern point from where I was standing. It was a steady sort of amber. Not blinking, not flashing, no red and green, nothing that belonged on anything I know that floats or flies. And it wasn't moving the way a boat moves. A boat at that distance has a rhythm to it, it lifts and settles, the light dips. This didn't dip. It sat.

I want to be honest that at this stage I wasn't excited. I was mildly annoyed, because if there was a boat inside the zone that was a problem and it was going to mean paperwork. I put my head in the bridge door and said something to the second mate, and he came out with the binoculars.

I'll call him V. He's Ukrainian, he's been at sea longer than I have, and he is the least dramatic human being I have ever met. He looked at it for a while and said, in the flat way he says everything, "That's not a boat."

Then he went in and looked at the radar and said there was nothing there, and then he stood looking at the radar for longer than a man stands looking at a radar when there's nothing on it. He told me later he'd had two returns in about a minute and a half that he'd have written off as clutter if he hadn't been looking out the window at the same time.

We had the Steiners, the 7x50s that live on the bridge, and I had them for a good couple of minutes before it changed range, and this is the part I've gone over the most, so I'm going to be careful with it.

It was a disc. I'm aware exactly how that sounds. I know that saying "flying saucer" in the year 2026 puts you in a particular category of person and I've thought about whether to use the word at all. But I'm not going to describe it as anything other than what it looked like, because the whole point of writing this down is that I saw a thing and I want to know what the thing was.

It was not the Hollywood shape. There was no dome on top, no windows, no ring of coloured lights. It was two very shallow bowls put together rim to rim — much flatter than you'd draw it, more like a lens, thickest through the middle and tapering out to an edge that looked genuinely thin. The rim was the clearest part of it. It had a hard, definite edge, and that edge is the thing that stops me being able to talk myself out of this, because haze and light and cloud and mirage do not have edges like that.

The colour was dull. Really dull. That's the detail I keep having to defend to people, because everyone expects chrome. It was the colour of wet slate, or unpolished pewter, or a stone you've just taken out of a river. It didn't reflect the sky and it didn't reflect the water. The amber I'd seen from a distance wasn't a light mounted on it. It was an area on the underside, roughly central, that was a warmer colour than the rest, and the way I've described it to the two people I've told properly is that it looked like the ring of an electric hob about a minute after you've turned it off. Not a beam. Not a spotlight. There was nothing coming out of it. It was just warm-looking.

And it wobbled. That's the word V used and it's the right one. Not a spin, not a tumble. It rocked slightly on its own axis, side to side, the way a coin does in the last second before it lies flat on a table. It did that the entire time we watched it. I've since found out that's a thing people report. I'd rather I hadn't, except that I said it out loud to V before I'd read a word about any of this.

It came closer while we were watching. Not fast. It covered what I'd guess was half the distance between us and where it started, over maybe a minute and a half, and then it stopped and sat again. I'd put it at a mile and a half out, three or four hundred feet up. I'm not going to give you a size, because anyone who tells you they can size an unknown object at an unknown distance over water is telling you a story. It looked bigger than a helicopter. That's all I'll commit to.

Two things happened then that I hadn't expected, and it's these two that I've been chewing on since.

The first is that it made no noise. I know that's in every one of these accounts and I know how it reads. But you have to understand what a working ship sounds like. We had generators running, we had thrusters going to hold us, there's a permanent hum you stop hearing after a day and only notice when it stops. So it's not that there was silence. It's that there was a thing hanging in the air a mile and a half away, close enough to have an edge, and it was contributing nothing at all to the noise of the world. Anything that holds itself up over the sea does it by pushing air down and pushing air down is loud. I've stood under enough helicopters.
