An Azerbaijan Airlines plane that crashed on Christmas Day was “likely shot down by a Russian military air defence system,” a UK-based aviation security firm has said. The community is coming together to remember a man killed in a Waukesha County crash that happened on Tuesday, Dec. 24.

Increasing analysis suggests Russian air defenses might have downed Azerbaijan Airlines flight J2-8243, which crashed in a ball of fire near Aktau,Kazakhstan on Wednesday morning, killing 38 of 67 passengers and crew.

Authorities in Kazakhstan are investigating the cause of an Azerbaijan Airlines plane crash in the country, which killed 38 people and injured 29 others on Christmas Day. The big picture: Flight J2-8243 was diverted while en route from Baku, Azerbaijan's capital, to Grozny in southern Russia.
