Ran out of runway otherwise would not have had to brake so hard.
Do you all think it was the brakes going out or even one side locked that made plane spin or pilot did it so as not to go off end of the runway?
I took an Airport Engineering course and some airports have EMASes (Engineered material arresting systems) at the ends of the runways to "trap" the aircraft if they overshoot. EMASes are filled crushable cellular cement material.

Crashed Boeing 757 pilot reported fault to tower and asked for space for emergency landing
A DHL cargo plane, which reported hydraulic problems when it was in flight,
made an emergency landing on Thursday morning at Juan Santamaría Airport.
Once on the ground, the aircraft went off the runway, its tail split and part of its landing gear broke. Only the pilot and co-pilot were on board, who did not register serious injuries.
In an audio that transcended, the pilot is heard alerting the terminal control tower: "Mayday, mayday, mayday, we have left hydraulic system problems. We have two souls on board. We have two thirty hours of fuel. We are going to prepare our aircraft to be able to make an emergency landing," he says.
According to the report of the Fire brigade, at 10 a. m. the aircraft Boeing 757 200 reported the mechanical damages when he went in flight to Guatemala, and therefore had to land on the track at 10:25. m. In the videos that have been released, you can see that the plane moves forward along the runway and during braking maneuvers, makes a 180 degree turn and wrong track.
During this last phase, a lot of smoke came out of the aircraft, as a result of the burning of the tire rubber or due to the evaporation of hydraulic fluid.
Firefighters activated their code for emergencies with units from the airport, as well as from the Alajuela, Heredia and San José stations. "The aircraft lands proceeding from the west on runway 07, turns south on the kilo taxiway and skids leaving the taxiway towards the green area in front of the Fire station," the report details.
Emergency care.
"When the aircraft touches down, initially the landing seems normal, but in the final run the aircraft slides to the south side of the runway, turning and part of its fuselage splitting. Our units immediately mobilized, placed ladders to remove the pilot and the copilot (Guatemalans), who had some minor blows, but were in good condition.” said Hector Chaves, fire director.
Then, foam was thrown at the site, as a spill was expected on the left wing of the plane, which was the one that hit the ground with the most force.
In addition, a small dam was made with heavy machinery so that the fuel did not advance to the sewer, and the Costa Rican Oil Refiner was in charge of extracting the rest of the fuel to minimize dangers.
Luis Miranda, deputy director of Civil Aviation, explained that the plane took off from Costa Rica and was heading towards La Aurora International Airport, in Guatemala City. The problems were reported 56 kilometers north of Juan Santamaria Airport, at an altitude of 19,000 feet (5.8 kilometers), when he announced that he should return to the terminal.
"He requests to go to a waiting point located 25 miles southwest of Juan Santamaría to make verifications," Miranda said. In this case, the pilot reported problems with the hydraulic system, which facilitates the operation of the flaps (ailerons), as well as the landing gear.
According to historical records, this Boeing 757-200, with registration adrianema HP2010DAE, had more than 22 years in operation. Since December 1999 it operated for Far Eastern Air Transport, with Taiwanese flag; in 2010 it passed to Aerolease, and in November of the same year, to DHL Aero Express. Given the damage suffered, the ship cannot be rebuilt and could be sold only in parts.
Total affectation.
Shortly before noon, the emergency was declared under control and rescue teams took it upon themselves to check the cargo inside the plane. In parallel, operations at the Santamaría were suspended until 3:30 p.m., while the conditions of the runway were being studied.
Aeris, the company that manages the terminal, said that it "worked quickly in coordination with the respective authorities to respond to the emergency this morning (yesterday Thursday) and facilitate the opening, as well as the conditions
of service for airlines and passengers."
Due to international aeronautics regulations, flights cannot be restored until minimum safety conditions are guaranteed on the runway. In this case, the 757 was crossed right at the exit of the fire station. This forced to modify the operation of the terminal, because at least until Friday the parallel south runway, which works for the loading of aircraft, was closed.
Ricardo Hernández, executive director of Aeris, said at 3:40 p.m. that, in total, 28 incoming flights were affected: 21 canceled passengers, six diverted to Liberia and a cargo ship that did not fly. In addition, 29 flights also did not leave, two of them charged. The plans were coming from or heading towards the United States, Central America, Mexico, Canada and Europe. This affected the itineraries of approximately 9,000 passengers.
Just at that time (3:41 p.m.) the first Iberia flight landed, coming from Madrid, which did not need to be diverted to Panama. In the meantime, hundreds of users suffered inconveniences and drowsiness when they did not know if their flights would depart or they would miss connections.
Jacqueline Arroyo, a neighbor of the airport, said that she does not remember a similar event in the area.
"My neighbor told me that a rumble had been heard; we heard it, but we didn't think it was an airplane. We thought it was a shock, but never in life had anything like this been seen here. It's dangerous because if that had exploded, we're all leaving here; the first thing we did was grab the K*ds and I grabbed my dog to go on the run," he said.
Meanwhile, Yalitza Salazar said that first she heard the normal sound of an airplane on the runway and then, as if a bomb had exploded.
On Monday, May 23, 1988, LACSA flight 628 bound for Managua and Miami, Florida, had a failed takeoff and crashed a few meters from the perimeter mesh of the Santamaría. Although the Boeing 727-100 was completely destroyed and with partial fire, the eight crew members and the 16 passengers survived.
"MAYDAY', 'MAYDAY', 'MAYDAY' (...). WE HAVE TWO THIRTY HOURS OF FUEL. WE ARE GOING TO PREPARE OUR AIRCRAFT TO BE ABLE TO MAKE AN EMERGENCY LANDING."
