Does it matter when the pilot didn't stay on the runway?

Video shows at least one side the flaps were not at zero, other side isn't clear. That might matter.

A Let L-410 Turbolet is about 15 meters long.
About 30 to 40 meters after the plane started to accelerate it start to turn right.
Can flaps really be the cause to what happened?
Or problem with the nose wheel perhaps?
Some witness said that the plane had problem with the rudder...

"The plane literally hit the ground and bounced - it was clear the pilot did not have total control of the plane, it bounced again," she said.

Boeing 737 goes for a swim

A passenger plane slid off a runway in the US state of Florida on Friday night, ending up in a river after landing during a thunderstorm.

LOS ANGELES (KABC) -- Eyewitness News has learned that a critical Los Angeles International Airport radar system that's meant to help prevent planes from colliding on the tarmac has failed on a routine basis over the last 18 months.

The radar system is known as the ASDE-X and when it breaks down, the screen air traffic controllers use to help track aircraft and vehicles on the ground goes blank.

A whistleblower air traffic controller at LAX tells Eyewitness News that the repeated failures of the ASDE-X system is "a disaster waiting to happen."

"For days or weeks at a time we are left without a necessary piece of safety equipment," the controller says. "At LAX, the entire airport community is not visible from the tower and the ASDE-X is our eyes."

Wind-shear and cross-winds during landing can make life "quite exiting", add to the mix a half decent thunderstorm and multiple contacts with the tarmac can be expected.
All very well if one enjoys roller coaster rides, but otherwise no so much fun.
I've had a couple of approaches where the plane has been hit by a sudden crosswind just before the tyres hit the runway, and both have resulted in go-arounds, and one that was just after the tyres hit the runway and we used the whole width before the pilot got things back in order, and that wasn't in a particularly violent storm so I can well see how a neo-tropical storm can cause multiple bumps on the runway followed by departing the tarmac for whatever is nearby.

(Reuters) - A component meant to slow an aircraft on landing was inoperative on the Boeing jetliner that slid off a runway into a river at a Florida military base, injuring 22 people, investigators said on Sunday.

The failure of the left-hand “thrust reverser” on the Boeing 737-800 was one of the factors investigators were looking at, as well as a request by the pilots to change runways, said National Transportation Safety Board Vice Chairman Bruce Landsberg.

Many people do very, very, very stupid actions regarding their safety. Just our human condition when faced with death.
The possibility that passengers would stupidly remain while attempting to break open locked compartments should not be dismissed.

Jamillah Foster was inside the house when the plane crashed into the front of her house. She told the AP no one in the house or outside on the ground was injured.

The plane’s occupants were taken to a hospital. Their identities and conditions are not known, but Foster said both appeared to be alert.

When this occurs, the MD-80 maintenance manual calls for turning off the automatic reverse thrust system, finding the cause of the excess temperature, and correcting the cause before turning the system on again.
Allegiant, however, did not determine the cause of the excess temperature, the FAA alleges. Instead, the carrier deactivated the system on April 14, 2018, and installed an inoperative placard on it.
Between April 14, 2018, and April 22, 2018, Allegiant operated the MD-88 on 28 passenger-carrying flights without determining the cause of the excessive engine exhaust gas temperature, the FAA alleges...

Five years ago, the flight vanished into the Indian Ocean. Officials on land know more about why than they dare to say.

.... The idea that a sophisticated machine, with its modern instruments and redundant communications, could simply vanish seemed beyond the realm of possibility.
