Nabil Attia Corvo, Driller, Who Lost Ninety Metres Of Rod Under Khafre
He felt the string go weightless at 211.4 metres in March 1978, wrote it down that evening, and wrote to the inspectorate ten times over forty-four years. Nine letters went unanswered. His daughter kept the log in a biscuit tin.
HELWAN, Egypt — The log says 211.4.
It says it on page 41, in ink, in a column he had ruled himself with a folding rule the night before the rig went on site: 211.4 — rod free, no return, 9m in 4 seconds. The time in the margin is 14:20. The date is 17 March 1978.
Nabil Attia Corvo, who was holding the string when it happened, died on 3 July at Helwan. He was 88. The cause was pneumonia, following a fall in May.
He spent forty-four years trying to get one line of his own handwriting into a file that had already closed.
What a foreman feels
He was born at Damietta in 1938, the son of a Nile ferryman, and came to Helwan as a boy when his father took work at the cement plant. He went on a rig at 21, drilling water bores at Wadi Natrun, and stayed on rigs for thirty-five years.
Drilling in 1978 was read through the hands. You feel the weight of the string, the bite, the change in the note the rods make. Ghareeb Salama Wassef, who was 31 that March and is 79 now, put it this way before we had shown him any document at all:
"It went light. You know it before you know it. Nabil had both hands on and he said stop before the winchman had touched anything."
Nine metres in four seconds. Then nothing to push against, and no return of the flush.
The invoice
This is the part of the story that does not rest on anybody's memory.
Two days later, on 19 March 1978, the contractor hired ninety metres of replacement drill rod from a plant firm in Cairo, priced by the metre. The invoice is in the daughter's possession and the hire firm's successor confirmed the series and the rate from its own ledger this month.
You do not hire ninety metres of rod on a Sunday because a shift went quietly. You hire it because ninety metres of your own is at the bottom of a hole you cannot get it out of.
Ten letters
The sounding's covering summary reached the ministry in June 1978 and ran to four lines. It concluded that no feature of significance had been encountered. The 31-page technical annex behind it carries his reading at page 9, unaltered, which this desk reported separately this morning.
He wrote to the inspectorate in 1979 and again in 1984, 1988, 1994, 1999, 2004, 2009, 2013, 2016 and 2019.
All ten letters survive, with certificates of posting for six. They are not angry. Three paragraphs each, a copy of the page enclosed, and the same request: that the log be entered on the file as an attachment, so that whoever came later would find it there.
He never once altered the reading, sharpened it, or said what he thought was down there. Across forty-four years and ten letters the wording of the entry is identical, to the decimal.
Nine of the ten went unanswered. The tenth, in February 2019, came back as a stamped registry slip acknowledging receipt and nothing else. His daughter says he had it framed and hung it in the hall, and that she thought at the time this was a joke and now does not.
What he lived to see
The first satellite radar passes over the plateau were flown in 2000, twenty-two years after his shift. This newspaper bought four of them last year, PX-1912, and on 9 August a drill string went free into open air at 703.4 metres about forty metres from where his rig had stood. The camera that followed it down came back with coursed walls, two dressed corners and a floor of fitted slabs.
He had been dead five weeks.
The registry's head of registry has answered us at length, and the answer is at the foot of this page. It is not a denial. It is an explanation of how a closed file works, and it is the most damning thing anybody said to this desk all summer.
What the tin held
Zeinab Attia Corvo kept the log in a biscuit tin on top of a wardrobe for three years before her father died and eight weeks after. She gave it to this newspaper with no conditions, declined a fee twice, and asked one thing: that we photograph the tin as well as the book.
"He was not a mystic," she said. "He was a foreman with a bad back who could not stand a number being wrong in a book. That is the whole man. Everything else people are going to say about him this week, he would have thought was silly."
He is survived by his daughter, three grandchildren, ninety metres of rod that nobody has ever gone back for, and one line of ruled paper that has now, forty-eight years late, been printed somewhere.

Sources & Method
His daughter wrote to this desk in July, three weeks after the funeral, enclosing a photocopy of one page and asking whether it was of any use to anybody. We photographed all 61 pages, had the paper and ink examined by a conservator, and matched the entry to a rig-hire invoice and an employment card she also held. We then traced the four-man crew and found two of them alive.
Who we spoke to
- Zeinab Attia Corvo, His daughter; a schoolteacher at Helwan. Interviewed twice at her flat; gave this newspaper the 1978 daily log with no conditions attached July and August 2026 Declined payment. Asked only that we photograph the tin as well as the book, and we have.
- The 1978 daily log, 61 numbered pages, hand-ruled, ink and pencil, one season. Given to this newspaper; photographed page by page and published entire with this obituary July 2026 Paper and ink examined by a conservator, who reports both consistent with the date and finds no page removed or replaced.
- Ghareeb Salama Wassef, Roughneck on the March 1978 crew; 79. Interviewed twice at Helwan, the first time before he was shown any document July 2026 Described the drop, the four seconds and the argument that followed it, unprompted.
- Sabah El-Din Rifaat Nashed, Rig mechanic on the same crew; 81. Interviewed by telephone after being shown a photograph of the log page, which was our mistake August 2026 His account matches. It is worth less than Wassef's and we say so in the text.
- The rig-hire invoice and his employment card, Plant hire, Cairo, 19 March 1978; card issued 1971, endorsed to 1994. Both in the daughter's possession; the hire firm's successor confirmed the invoice series and rate from its own ledger August 2026

What we could not confirm
- Whether ninety metres of drill rod is still in the ground under the causeway. The 1978 annex gives the borehole collar to the nearest ten metres and records it capped. A magnetometer run over that square would answer it in an afternoon and needs a permit this newspaper applied for in May, which has been neither granted nor refused.
- What the inspectorate's observer wrote. The hire invoice carries a fifth man, entered only as 'insp. obs. — S. Bishara'. His field notes are not in the file the registry produced for us, and the registry says pre-1984 field notes are on cards in a store that has been under cataloguing since 2019.
- Whether the void his rod dropped into is the one a camera reached this month. The coordinates agree to within forty metres and the depths do not agree at all — 211.4 against 703.4. Both readings can be right and describe different things, and no survey yet run ties the two together. A tie-in survey would take an afternoon and needs a licence that has never been issued.
