So has anyone got any temperature and wind information ( presumably from online) so the above post can be used meaningfully?
Both winds and temperature were pretty standard, nothing special. See this graph:
Blue line is wind speed and red line is direction. X-axis is atmospheric pressure and this incident happened somewhere around 430hPa (a little to the left of centre). Of course, this data is slightly uncertain (it's from a forecast model, not an actual observation) but I don't see anything to suggest there'd be a much windshear at their altitude.
