At some point in the last 5 years I put together this matrix of Space Shuttle Main Engine test failures. The last 6 columns are documents which describe some of the incidents in more or less detail. I got all the documents off the NASA Technical Reports Server (NTRS).
However, and I blame the ravages of advancing age, I no longer have the document known only by the mysterious nomenclature "AL-TR-898-013" and I can't currently find it on NTRS or anywhere else. Naturally, it's the one that contains the more or less complete list of incidents.
I know sometimes documents are removed from NTRS and that may well have happened here in which case I'm probably out of luck.
I've checked my computer backups but they only go back a year.
I'm guessing it's a Marshall Space Flight Center technical report, but if anyone can point me to a copy of this document - or even tell me what the title of it is -, I'd greatly appreciate it.
