The 1977 flu pandemic was unique because it killed the young more than the old. This is because the old people had been through the 1950s H1N1 outbreak and had immunity.
This study from 1978 shows that the 1977 flu was genomically very similar to the H1N1 from the 1950s. This strain vanished off the face of the Earth for 20+ years and then re-emerged largely unchanged. The odds of that are basically zero. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2395678/?page=1
This 2014 report from the center for arms control and non-proliferation reveals that relevant scientists in the late 70s knew it was a leak but hid it.
As this paper reports, the academic community didn't begin to acknowledge the lab origin until around 2008 and didn't begin to do so in an official capacity (academic papers) until 2009. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4542197/
