Beautiful find there. The SPAN guy (who's voice sounds familiar) was complaining about how he's "been awful busy running around doing 15 million things" [33:24:02] and later "we got three or four little ditties going on with the spacecraft".
If he's busy at 33:24 I wonder how he'll feel in 24 hours?
The clip is also culturally significant and interesting [somewhat reminds me perhaps a bit of the scene where Miss Scott calls General Turgidson in the war room, at the end of which Turgidson tells Scott to be sure and say her prayers].
I don't think it's possible to determine the precise "spooky story" that the woman was reading, but in theory it might be possible to figure out the James Cagney "murder mystery" she was watching on April 12, 1970 in which Cagney has "knives." This would have been broadcast at about 9:00 PM in Florida.
