I wonder if 3 launches to orbit in 67 minutes is an all-time spaceflight history record...
Indeed it is! I quickly parsed launch.tsv from @planet4589's GCAT. The previous record-holders were:Dec 12 1970, when Explorer 42, Kosmos-385, and Peole launched within 131 minutes, andApr 29 2021 when Pleiades Neo 3, Tianhe, and Starlink-26 launched in 114 minutes.
For fun, my minified, tweet-size Python code with open('launch.tsv') as f: e = f.readlines()[2:] p = [l.split('\t') for l in e] d = [s[1] for s in p if s[20]=='OS'] for t,n in zip(d,d[2:]): m = float(n) - float(t) if m < .1: print(t)
