Preliminary information from the scene of the Aria Air Ilyushin Il-62 crash in Iran indicates that the aircraft was a Kazakh-registered jet.
Aria Air's aircraft have various colour schemes but images of the wreckage in Mashad clearly show a red vertical fin with the 'Aria' lettering, consistent with the aircraft registered UP-I6208.
Meteorological information from the reported time of the accident, 18:10, does not point to poor weather.
But the wind direction - from the northeast at 14kt - would be experienced as a crosswind on Mashad's runways, which are aligned northwest-southeast.
Il-62s have four rear-mounted engines and the type has a retractable tail-wheel which can be deployed to support the aircraft while parked.
The jet involved in the Iranian crash lost much of its forward fuselage structure, and came to rest tipped onto its empennage.
While earlier reports suggested 30 fatalities, this figure has been revised down to around 16.
