Again in the UK, "102 minutes that changed America" is starting on Channel 4 in a couple of minutes. Lots of amateur footage that I don't think has appeared on UK TV before (although it was aired in the US last year), & so should be worth a look.
I'm watching this as I sit at the dining table writing up a report, and it (the tv programme) is bloody well sobering. Those who spout claptrap about no planes, explosives, and the like would be well advised to watch it.
