Two Tests, Forty Years Apart, Both Windows Open At 23:40. Somebody Chose That.
Camp Hero's transmit authorisation for 12 August 1983 opens at 23:40 and closes at 00:20. So does the 1943 harbour trial's range-control sheet, to the minute. The scheduling memo gives the reason in one sentence.
A regular column. The views expressed are the writer's own.
MONTAUK, New York — The Camp Hero transmit authorisation for 12 August 1983 opens its window at 23:40 and closes it at 00:20.
The range-control sheet for the harbour trial of 28 October 1943 opens at 23:40 and closes at 00:20.
I am not going to tell you that those two windows resonate, or reach, or answer each other across forty years. I am going to tell you something duller and much harder to argue with: a man sat at a desk in the second week of August 1983 and wrote the second window to match the first, and he wrote down why he was doing it.
The eleventh line
The scheduling memorandum is dated 9 August 1983, three days before the window. It runs to eleven lines. Ten of them are about generator fuel, a duty roster and a request for a second cook.
The eleventh reads, in full:
Window to be set 2340–0020 local, to correspond with the window recorded for the harbour trial of 28 October 1943 (ref. B/1943/DE-173), per Dr. Rooke-Vaszary's note of 4 May, RH-6/114-C.
That is the finding. Not an inference from two matching numbers, which would have been worth a paragraph. A citation — series, number, date — from the person setting the second window, to the record of the first.
What the two sheets are, and what they are not
The 1983 document authorises. It does not log. It says that between those two times the transmitter may go on the air, and it is signed twice and countersigned in a different ink. It is not evidence that anything radiated, and I will come back to that.
The 1943 document is a booking. Range control allocated water and air on a printed form. It is the least interesting paper in the folder, which is exactly why it survived. Nobody has ever culled a booking sheet.
Folder 21 holds forty-two of these for October and November 1943. Forty-one run from 22:00 to 02:00, which is what the standing night window was. One runs from 23:40 to 00:20.
Somebody narrowed that window in 1943, to forty minutes, and somebody else went and found it in 1983.
The arithmetic I am not going to do
It is 14,533 days between the two nights.
That number is not a multiple of anything interesting and it is not round in any base a human being uses. I have had eleven reader letters this month doing arithmetic on it, three of them very good. When you have a memorandum that states the reason in one sentence, you do not need a calculator.
What this desk did wrong
We were sent the 1983 sheet on 11 June 2024. It went into a folder we label received, unplaced, and it stayed there for twenty-six months.
The reason is not a good one, and I am the person who filed it.
12 August 1983 is not an ordinary date. It has been in print, on tape and on stage since before it happened. When a document arrives carrying a date you have already met in folklore, the document starts at a disadvantage it has done nothing to earn. We treated the provenance of the story as though it were the provenance of the paper. They are different objects, held by different people, and one of them had an index and a release letter.
This is the second time this month we have been wrong about this site in the same way. Our August piece on the meters concluded Camp Hero went dark in 1981; a colleague showed earlier today that we had asked a utility for records of a circuit nobody was billed for. Both errors have one shape. We let the form a source arrived in decide what we did with its contents.
The only document this newspaper keeps in its own vault about its own conduct is PX-2161, a study protocol we signed and published before we approached a single participant, on the ground that a protocol which appears after the result is not a protocol. A filing rule that appears after the embarrassment is not a filing rule either. We are writing one this week and we will publish it.
What the window was for
I do not know, and neither does anybody who would talk to me.
The memorandum gives the reason for the timing. It gives no reason for the test. It cites an authority — the Rooke-Vaszary note of 4 May 1983, file RH-6/114-C — and that note is not in the released tranche, is not in the index of the tranche, and has been the subject of a request sitting unanswered for 174 days.
Cdr. Beckington-Mwangi, whose reply is below and who thinks my headline outruns my evidence, confirms the RH-6 series exists, that it was accessioned in 1991, and that she can find the accession number and not the boxes.
Somebody chose 23:40. That is a smaller claim than the one most people want from this site, and it is the one this paper can put its name to without a footnote.
The larger claim is behind a file number, and the file number is RH-6/114-C.

The Meridian TelegraphTHE 1983 DATE WAS ALWAYS REAL: MONTAUK'S OWN PAPERWORK SAYS SO
Took the memorandum's eleventh line, which we published, and treated a matched window as proof that the 1943 effect had been reproduced.
Had that we did not
The line itself, quoted accurately and in full, which is more than the last four pieces about this site managed.
Left out
That the memorandum explains the timing and says nothing whatever about the purpose, and that the authority it cites is a document nobody has.

A literary essay on anniversaries and the institutional appetite for re-enactment, using the two sheets as its opening image.
Had that we did not
The best account anyone has written of why a scheduler reaches for a date at all, and it is better than anything in this column.
Left out
The file number. Four thousand words and RH-6/114-C is never mentioned, which is the only object in this story that could still be obtained.

Cross-indexed two records releases by date rather than by subject, had both sheets read blind by a radar engineer, and printed the sentence that joins them.
Had that we did not
The memorandum entire, the 1943 booking set against the standing night window on the other forty-one sheets in its folder, and the naval office's objection at length.
Left out
We held the 1983 sheet for twenty-six months because the date reached us through folklore first. This column admits that in its fourth section. It belonged in the first, and a column that grades its own conduct is not the same thing as being graded. — V. Ashcombe-Doyle, standards editor

They Buried contacted Cdr. (ret.) Isaure Beckington-Mwangi, Director, Fleet Trials History Office in writing on 5 August 2026, with both sheets attached, nine numbered questions, and no deadline imposed. Replied 18 August 2026. Printed in full and unedited, including the paragraphs about our headline.
I will take your two documents in order and I will not dispute either of them, because they are what you say they are and pretending otherwise would waste your afternoon and mine.
The sheet from folder 21 is a range-control booking for the night of 28 October 1943. It books water. It does not describe a trial, it does not name an apparatus, and it does not establish that anything at all took place. This office holds something over four thousand of these for that year, and the overwhelming majority record a night on which somebody ran a compass swing or a degaussing pass and then went to bed.
You asked whether 23:40 to 00:20 is the standard night window for that series. It is not, and I am not going to tell you it is. The standing window on Fourth District sheets is 22:00 to 02:00, and your reporter is right that the other forty-one sheets in the folder use it. A forty-minute booking is a narrow booking. Narrow bookings exist for entirely dull reasons — a tide, a tug's availability, a boom that opens on the hour, a pilot who has somewhere else to be at one in the morning — and I can give you four such reasons without leaving my desk. What I cannot give you is the one that applies here, because the sheet does not say and the trial order it cites is not held in this building.
On your 1983 memorandum I have less standing and more to concede. It is not our document and not our service, and I will not interpret it for you. I will say one thing, because you asked plainly and a plain question deserves better than a shrug: the reference block you have quoted is a proper archival citation, with a series, a number and a date. That is the form a person uses when they have read the thing they are citing. It is not the form a person uses when they have half-remembered a paperback.
And on RH-6/114-C. You asked whether the series exists. It does. It is not held here and I cannot produce a page of it for you. I am told it was accessioned in 1991 and I can find you the accession number and not the boxes. I would rather write that sentence down for you than have you print that I refused to answer, because the first is embarrassing and the second is untrue.
What I object to is not your documents. It is the join. You have a booking sheet establishing that one window in 1943 was unusually narrow, and a memorandum establishing that a scheduler in 1983 knew how narrow it was and copied it deliberately. Between those two facts you have laid forty years of a story that grew up in paperback books and on stage, and your readers will carry that story across the join whether or not you invite them to. Your sentences are careful. Your headline is not. It contains the word 'chose', and 'chose' invites precisely the inference your own final section declines to make.
I would ask you to print, at the same size as everything else, the ordinary possibility: that a scheduler with an archive, a sense of occasion and forty spare minutes matched a window because it pleased him to, and that nothing whatever follows from it. I do not expect you to give that much room. But it is the reading I would put first, and I have read a great many more of these sheets than you have.
