The video shows emergency workers sawing away at the fuselage, which appears to have split in half, following the collision and resulting crash. Debris is strewn around amid the overnight commotion.

Investigators are at the scene examining evidence, taking fuel samples and talking to staffers.

Two main theories as to the cause are being considered at this time – an air traffic control error and the actions of the snowplow driver.

It has been determined at this time that “the driver of the snowplow was under the influence of alcohol,” spokesman of Russia’s Investigative Committee Vladimir Markin told the reporters on Tuesday.

The sensitivity of the matter has led to Investigative Committee head Aleksandr Bastrykin to hold a meeting with airport personnel and the investigative group, which was now joined by representatives from the International Aviation Committee as well.

Russian President Vladimir Putin has expressed his condolences over the Total CEO's death. TASS cited his spokesman as saying that "Vladimir Putin has long known de Margerie and had a close working relationship with him."

"The president highly appreciated de Mergerie's business skills, his continued commitment to the development of not only bilateral Russian-French relations but also on multifaceted levels," Peskov also said.

The small business jet was taxiing on the runway around midnight, but then collided with the snowplow.

The CEO of France’s oil and gas giant Total was the only passenger in the jet, while three crewmembers who were also French citizens perished as well.
