The "Aviation Expert" on my morning local news says that the pilot must have trained at Ringling Brothers.
It does look like the fire was caused by the landing, but I think it's a little too early to blame the pilots. There's a CCTV video that shows that the aircraft touched down way too fast and hard and bounced so hard that its gear failed on the second hit. It looks like parts of the main gear rammed up through the wings, which punctured the fuel tanks. The aircraft, however, had supposedly been hit by lightning and was suffering from electrical problems. The Superjet is a fly-by-wire aircraft with sidesticks that aren't physically connected to the control surfaces. If the lightning hit fried out parts of the computer systems or fried the wiring going to the motors that move the control surfaces, the pilots might not have had full control of the aircraft. We'll have to wait and see. Same with the accusations about people stopping to get luggage. If that bounce came down hard enough to destroy the main gear, the impact could have also caused damage inside the aircraft (such as collapsed luggage bins, a buckled cabin floor, or seats that broke loose) that prevented passengers from being able to reach the forward exits. Also, while I see that people are pointing at Mr. Khlebushkin (while also attacking his weight) as holding up the evacuation, some of the reports also say that Mr. Khlebushkin was the second person off the aircraft. If he was the bottleneck that prevented people farther back from escaping, wouldn't he be one the last off the aircraft and not one of the first?
