Yemenia Airways Flight 626 crash
Yemenia Airways Flight 626 departed from Sana in Yemen and crashed after an aborted landing attempt at Moroni in the Comoros Islands off the east coast of Africa on 29 June 2009. Meteosat-7 11.5 Âµm IR images (above) showed that there was a strong southerly flow over the region on that day, in the wake of a cold frontal passage. Meteosat-7 IR cloud drift winds from the CIMSS Tropical Cyclones site (below) showed that winds were generally in the 20-30 knot range over the region at the time of the crash.
These wind speeds are consistent with the surface METAR reports at Moroni Hahaya International Airport:
