Thanks to a response I received from Jason Atkinson at History Hub, I’ve managed to find Project Mogul R&D files at NARA – though these aren’t (yet) online, they do at least exist, which is a good starting point.
Oh, and I thought I’d include a quick log here of the other NARA files I’ve managed to find. Feel free to ignore this, it’s mainly for my own benefit. 😉
For Bureau of Aeronautics records (Record Group 72), I also found its LTA (Lighter-Than-Air) file (1916 – 1945), containing records that “were collected by a variety of individuals and organizations, including Charles P. Burgess, an expert in airship design within the Lighter Than Air Design Branch“. The downside is that it is “78 linear feet, 7 linear inches” long (comprising “63 Letter Archives Box, Standard; 70 Legal Archives Box, Standard; 2 Custom Box A1”).
I also found a file for “Balloons, Darex Sounding” – I was looking for this because David DeVorkin (p.286) mentions “the modified Dewey and Almy Darex J-2000 and Darex J-1100 balloon production samples”, which were being tested in 1947.
There’s also “Balloon Envelopes” in RG 342 (no additional information given, but it’s one of the R&D topics I’m specifically interested in).
Project Helios (which was run by NATEC at Lakehurst) has a list online of changes to project personnel from 3rd May 1947 to 2nd July 1947. This starts with Robert E. Bass, and then adds [name, id, rating]:
- BASTEDO Raymond W – 513 24 90 – AR1
- BLANCHARD Earl H – 206 25 96 – AERM1
- CLARK John E Jr – 250 56 41 – AR3
- COVELLA Robert L – 798 21 68 – AERM3
- EWING Jerry D – 224 77 19 – AERM3
- GLICKMAN William F – 238 80 71 – AR2
- HART Francis J – 201 62 62 AR3
- IAIN Sebastian (n) – 382 80 61 – AR1
- MAC MILLIAN Henry J – 224 49 51 – CAR
- WODZIENSKI Edward (n) – 202 56 04 – AMM1
All certified correct by W. A. Cockell, Capt, USN
Then 25 Aug 1947:
- CHAMBLISS Herbert – P26657599 – CETM
- BASS Robt E – 2742805 – CAERM
(Both moved to Ottumwa, Iowa)
Project Helios disestablished: Auth ChNavRes cer 12523 dated 23 May 1947 and suPers ltr.
Pers 21452-jah ser 16719 dated 25 June 1947.

There’s also this Project Helios record: A15-2 Project Helios SP Event. (I have no idea what this is, alas).
As far as Fort Dix goes, I found some files in RG 342 (though I don’t hold out a lot of hope for these):
- Fort Dix – Materiel Command Test Station
- 686 Fort Dix – 1 January 1947 to
- (686 = Army air bases and aviation fields)
- 600.1 Fort Dix – 1 January 1947 to
- (600.1 = “Building and grounds — Construction and installation”?)
- Fort Dix Army Air Base
- 333 Fort Dix – 1 January 1947 to 31 Dec 47
- (333 = Inspections and investigations by inspectors general and other officers, and reports.)
So, no Project Helios file for Larry Walters?
Tallulah: actually, Charlie Moore (of Project Mogul fame) attached a parachute harness to an early polyethylene balloon on 3rd November 1949 (“using sofa cushions from home”, according to Vaeth p.138), before “(taking) off over the Minnesota countryside”. So Larry Walters wasn’t the first sofa balloonist, sort of. 🙂
