### example output

# [06:50.140 --> 06:55.660]  So one of the things that you've been active in Washington has been dealing with UFOs.
# [06:55.660 --> 07:00.820]  You've established the all-domain anomaly restoration office.
# [07:00.820 --> 07:05.700]  I wonder what you could tell me about that, and I know that the report found that while
# [07:05.700 --> 07:10.740]  they were able to explain some of the things that the army and other people are reporting,
# [07:10.740 --> 07:15.220]  there were 171 unexplained situations.
# [07:15.220 --> 07:16.220]  Way more than that now.
# [07:16.220 --> 07:21.980]  So the most recent report that I got is they've looked at about 800, as opposed to the first
# [07:21.980 --> 07:27.660]  group of 300, unidentified aerial or anomalous phenomenon, because some's in air and some's
# [07:27.660 --> 07:29.820]  in water.
