Forty-One Minutes Of Camera At 703 Metres. The Walls Are Cut.
A 203mm hole reached 706 metres under Khafre and broke into open air. Three specialists logged the footage blind, told nothing of where it came from. The cave geologist among them wrote down masonry.
A months-long reporting project. Documents cited below are held in The Vault and available to readers.
GIZA, Egypt — At 08:47 on 9 August the drill string dropped 1.4 metres under its own weight and the torque at the rotary table went to zero.
The bit stood 703.4 metres below the Giza plateau. It was turning in air.
Thirty-two minutes later a 60mm camera went down the same hole on 800 metres of armoured cable. It ran for forty-one minutes. At 10:00 the daily working window closed — and 9 August was the forty-first and last day of the licence — so Insp. Ramez Soubhi Kadar raised his hand at the collar and the string came up.
Thirty hours after that the hole was filled with grout.
The walls in the footage are cut. That is the finding and this newspaper is not going to hedge it.
The licence, and what it was not
The 100mm hole we drilled on 2 August was an archaeological permit. Its renewal has been with the inspectorate since 14 July and has still not been decided.
This hole was something else. A class GI-2 ground-investigation licence, issued on 30 June by the plateau's structural safety unit: forty-one days, a bore of not more than 203 millimetres, work only between 06:00 and 10:00 before the site opens, and a ministry inspector at the collar whenever the rotary turned.
A GI-2 licence is for measuring ground. It does not permit excavation, it permits no sampling beyond drill cuttings, and — as Eng. Nadim Zaghloul-Farrar says at the foot of this page, correctly — it does not mention cameras at all.
The line was the third of the eight coordinates published by Corrado Malanga, Filippo Biondi and Armando Mei, recomputed by our two radar processors from the scenes in PX-1912. Collar to break-through: thirty-four working days of four hours each.
The log and the caliper
Two instruments recorded the void before any lens did.
The driller's log, kept by hand by Wagih Botros-Anany, reads at 08:47: rods drop 1.4m free, torque 0, no returns, no water. Open at 703.4. Air. The circulation fluid stopped coming back because there was nowhere left for it to come back from.
The caliper — three sprung arms that measure the width of a hole — was run on the way out. From the collar down it traces 203 to 211 millimetres. At 703.4 metres it opens past its own stop, 340 millimetres, and stays pinned there for the remaining thirty-four metres of cable.
An arm pinned at its stop is an arm in a space wider than itself. That is a measurement, and it was taken before anybody saw anything.
Three people who were not told
We sent the forty-one minutes to three specialists who were not told the country, the depth, or the reason.
Ingrid Sørbø-Ochieng surveys underground for a Swedish iron mine. Dr. Marisol Quintanar-Feld is a karst geologist who has spent twenty-six years in limestone caves. Emeric Vasilakis-Nnamdi conserves cut stone in Athens.
Each was paid the same fee in advance. Each had to file, in writing, what they expected to see before the file would open.
Quintanar-Feld's expectation, in full: Solution cavity in carbonate. Expect scalloping, irregular section, no planar surfaces.
Her log, written blind, three hours later: Not karst. Coursed masonry, regular bedding, dressed faces. I would like to be shown the rest of this footage before I sign it.
All three logged courses. All three logged a level floor. Two of the three measured the course height independently and both got 0.52 metres.
What is in the forty-one minutes
The camera enters the void at 703.4 metres and falls free on the cable to a floor 38.6 metres below.
The walls are worked stone in regular courses. Sørbø-Ochieng measures the module at 0.52 metres over eleven visible courses and calls the variation "within what I would accept from my own crew".
Two dressed corners are in shot, at 89.4 and 90.1 degrees.
The floor is fitted slabs, level across the full width of the light. Vasilakis-Nnamdi notes tooling marks running one way on four faces, and says he would date the technique from them if anybody would let him near the rock.
The lamp reaches about twelve metres. On three sides the space goes past it.
The grout
The works order is dated 10 August, timed 16:12, and calls for 4.1 cubic metres of cementitious grout pumped from the collar. Eng. Zaghloul-Farrar signed it.
He has not watched the footage. He says so himself below, and explains why. Read it twice: it is the most incriminating paragraph on this page, because in order to refuse the film he first has to concede the hole.
What this desk takes from it
The argument has moved, and nobody announced that it had.
For eighteen months the question was whether a satellite can see six hundred metres into rock. It is now whether a space with square corners and a fitted floor, seen by a camera anybody can hire for a week, is worth a licence that runs longer than forty-one days.
The hole is grouted. The coordinates are published. The footage is in the vault entire, including the eight minutes where the camera spins on its cable and the picture is unusable.

Sources & Method
We applied for a class GI-2 ground-investigation licence on 2 June, separately from the archaeological renewal that is still with the inspectorate, and co-funded the borehole with the contractor that drilled our first hole. The line was the third of the eight coordinates in the Malanga, Biondi and Mei survey, recomputed by our two SAR processors from the scenes in PX-1912. We then did the thing that actually matters: we sent the footage to three specialists in different countries who were told nothing about where it came from, paid them in advance at the same rate, and required each to file in writing what they expected to see before they were allowed to open the file.
Who we spoke to
- Ingrid Sørbø-Ochieng, Underground survey engineer, Kiruna. Sent the footage with no location, no depth and no context; log published entire 11 August 2026 Measured the course module over eleven courses at 0.52m. Believes the surfaces are tooled, not sawn.
- Dr. Marisol Quintanar-Feld, Karst geologist, Ljubljana. Same footage, same conditions; wrote and filed her expectation before viewing 11 August 2026 Expected solution cavity in writing. Logged masonry. Asked to see the rest of the footage before signing.
- Emeric Vasilakis-Nnamdi, Stone conservator, Athens. Same footage, same conditions; log published entire 12 August 2026 Notes tooling marks running one way on four faces. Will not date the technique from a lens.
- Faridah Osei-Lindqvist, Site engineer for the Cairo contractor that drilled both holes. Interviewed at the collar and again by telephone; supplied the drill log and the caliper trace June–August 2026 Has worked the plateau since 1994. Her firm is named in the licence and has asked us not to name it.
- Eng. Nadim Zaghloul-Farrar, Director, plateau structural safety unit, Ministry of Tourism and Antiquities. Sent the full draft, the log, the caliper trace and the footage; replied in writing after nine days August 2026 Signed the works order that grouted the hole. Printed in full under Right of Reply.

What we could not confirm
- Whether the floor is the bottom of anything. The camera's lamp reaches about twelve metres and on three sides the room goes past it. We have seen one lit patch of one space and we cannot honestly call it a room, a chamber or a hall. It is a floor with walls on two sides of it.
- What the stone is, and when it was cut. Three specialists who were told nothing logged coursed masonry, two dressed corners and a fitted floor, and this newspaper accepts that reading. What none of them can give us is a date, a quarry or a tool, because the licence permitted no sampling beyond drill cuttings and the cuttings from the last forty metres came up as dust or did not come up at all. A fragment the size of a thumbnail would answer all three questions. No licence issued for this plateau permits one to be taken.
- Whether the forty-first day was the forty-first day by accident. The licence ran 30 June to 9 August. The string broke through at 08:47 on 9 August, one hour and thirteen minutes before the last window of the last day closed. We have asked twice whether a longer licence was ever considered and have had no answer to that question, as opposed to no answer at all.

Our headline sells the minutes. The only reason this story stands up is that three people were paid in advance, told nothing, and asked to write down what they expected before they looked. That design is in paragraph fourteen and the drama is in the first line. — V. Ashcombe-Doyle, standards editor

They Buried contacted Eng. Nadim Zaghloul-Farrar, Director, plateau structural safety unit on 11 August, in writing, with the drill log, the caliper trace, the works order and the full forty-one minutes. Replied 20 August. Asked that it run whole. Printed unedited, including the parts about this newspaper.
I will begin with what I am not going to dispute, because your readers will assume I am disputing everything and I am not.
There is a void at 703.4 metres. I have the same drill log you have; my inspector countersigned it at the collar within the hour. The rods dropped, the torque went to zero, the circulation fluid did not come back. I read the caliper trace before you did. An arm pinned at its stop for thirty-four metres is a space wider than the tool, and there is no reading of that trace which is not a space.
So: a void, of at least thirty-four metres of unobstructed drop, at 703.4 metres, under the Khafre pyramid. I am the person who signs for the ground under that monument and I am telling you in print that it is there.
Now the part you have written your story to make me say, and which I am not going to say.
I did not watch your film. I am not going to watch your film. You have taken this as evasion in three separate emails and it is not evasion, it is the whole of my job. A class GI-2 licence authorises the investigation of ground. It authorises a bore, a caliper, a gamma tool, a sonic tool, cuttings, and a report. It does not authorise a camera, it does not mention a camera, and the reason it does not mention a camera is that a photograph is not a measurement of ground and cannot be entered into a structural calculation. My signature on that works order is a structural signature. If I watch your film, I have looked at evidence of a class my licence does not admit, and every number I have certified for the plateau since 2019 becomes contestable by anybody with a lawyer.
On the thirty hours. The condition is seventy-two and I signed at thirty, and you have printed that as though the speed were the confession. The speed was the void. A 203-millimetre hole standing open into thirty-four metres of nothing, under a plateau that carries eleven thousand people on an ordinary Tuesday, is a route for water and a route for loss of ground. I have seen what a much smaller hole did to a much less important street in Alexandria. I grouted it in thirty hours because seventy-two was written by somebody who did not know the hole would find air, and I did.
You want me to have sealed a chamber. I sealed a hole. Whatever is at 703.4 metres is exactly where it was on the eighth of August, undisturbed, and it will be there in fifty years, which is more than I can say for anything that is dug at speed by people who are being written about while they dig.
And since you asked me the question three times: no, I did not refuse a longer licence, because I was never asked for one. The application in front of me was for forty-one days and I granted forty-one days. If your newspaper wanted ninety, your newspaper should have written ninety on the form.
What I will say, and you may hold me to it as you held my colleague to hers: the void is now in my unit's ground model, on my instruction, as a confirmed feature and not a reported one. That is a permanent change to the document every future work on this plateau is assessed against. It happened because you drilled. I would rather have found it myself.
