Known metadata gaps

Recorded explicitly rather than guessed.

doi is null: the technical memorandum carries a NASA report number, NASA-TM-103472, rather than a DOI.
NTRS gives the publication date only as 1989; evidence that speaks as of the memorandum is scoped historical as of 1989-01-01, which stands for the year and not for a known day.
The PDF text layer is OCR of a typescript with frequent recognition errors (“r_In” for resin, “_ te_._erature” for a temperature); every passage cited was read against the page and no OCR string was carried into evidence. Pages 9–19 are figures and were not used.
Temperatures are printed in degrees Fahrenheit and are carried in claims as the source prints them; none is converted.
Lineage unresolved: this memorandum is an explanatory overview of carbon–carbon composite development drawing on NASA and Department of Defense programmes; the upstream works behind the passages cited are not named in it and are not registered in this corpus, so its independence from the other composite sources is not established.
