Crikey. At first I thought this was another view of the shootdown seen last month, but when I saw the end result this clearly is a new event.
That was quite some explosion, much bigger than I would expect from a manpad (of which I could see no trail) or fuel tanks going up. If it was ordnance on the aircraft cooking off then what the hell were the carrying.
It's sometimes quite difficult to tell who are the goodies and who are the baddies in conflicts like this, but regardless I think most military aviators have a level of mutual respect even across lines of conflict, and so yes, poor guys. As an ex RW mate, that was pretty horrible to watch.
