Good memory! Well, kind of ... here is the NTSB Report on the crash (PDF): https://www.ntsb.gov/investigations/AccidentReports/Reports/AAR9706.pdf https://www.ntsb.gov/investigations/AccidentReports/Reports/... - its interesting: Planes back then had an emergency oxygen system that worked on the same principles like the candles mentioned above, but these were much smaller. The crashed plane transported discarded / expired oxy generators in loose cardboard boxes since they were not labled as hazardous materials. One of theses generators was probably the cause for a chain reaction and the crash.
