At least 41 people were killed when the Sukhoi Superjet 100 bounced along the tarmac before the rear of the plane suddenly burst into flames on Sunday night.
A 22-year-old American named Jeremy Brooks was among the 41 people who died on the flight, his boss from a local fishing shop in New Mexico told NBC News. The US State Department confirmed the death of an American in the crash.
Brooks had recently graduated from Colorado College and had taken a job as a fishing guide in Russia, shop owner Ivan Valdez told NBC News. The graduate was on his way to Murmansk where he planned to take a helicopter flight to a fishing camp.

Survivor Pyotr Egorov said the plane appeared to have been hit lightning.
"We were so scared, we almost lost consciousness," the Komsomolskaya Pravda daily quoted Egorov as saying. "The plane jumped down the landing strip like a grasshopper and then caught fire on the ground."
Video captured at the scene showed passengers leaping from the wreckage onto an inflatable slide and people clinging to their luggage as emergency vehicles sped toward the jet.
