46750 feet, 345 mph, 29 hours

Fossett, according to Channelnewsasia.com, was at 46750 feet, that’s 14250 metres, having been aloft for almost 29 hours, and travelling at speeds of around 300 knots, (345 mph, or 555kph). In other words about 50000 feet/15000metres, and around 30 hours…have they not heard of rounding? We don’t need five sig figs in a news story, in a scientific paper yes, but not a news story…
