A look at recent aviation disasters in North America

The crash of a Delta Air Lines plane in Toronto is the fourth major aviation disaster in North America in the last month.

Here's a look at each of the crashes.

A Delta plane arriving Monday at Toronto’s Pearson Airport from Minneapolis flipped and landed on its roof, injuring at least 17 people.

The airport confirmed that an “incident” occurred Monday with the Delta flight and that all 80 passengers and crew are accounted for. Ornge air ambulance said it was transporting one child to Toronto’s SickKids hospital and two adults with critical injuries to other hospitals in the city.

Video from the scene showed the Mitsubishi CRJ-900LR upside down on the snowy tarmac as emergency workers hose it down.

According to the Meteorological Service of Canada, the airport was experiencing blowing snow and winds of 32 mph (51 kph) gusting to 40 mph (65 mph). The temperature was about 16.5 degrees (minus 8.6 Celsius).

Endeavor Air, based in Minneapolis, is a Delta subsidiary and the world’s largest operator of CRJ-900 aircraft, a popular regional jet developed by Canadian aerospace company Bombardier.

The Federal Aviation Administration said in a statement that the Transportation Safety Board of Canada will head up the investigation and provide any updates.

A small commuter plane on its way to Nome crashed on Feb. 6, killing the pilot and nine passengers.

The Bering Air single-engine turboprop Cessna Caravan was traveling from Unalakleet when it disappeared about an hour after taking off. The Coast Guard said the aircraft went missing about 30 miles (48 kilometers) southeast of Nome.

After a wide search, the plane’s splintered body and debris were found the next day on the sea ice.

The day of the crash there was light snow and fog, with a temperature of 17 degrees (minus 8.3 Celsius).

The commuter flight was part of a workhorse network of short-hop flights that people in the immense and rugged state rely on to get to medical appointments, attend work meetings, buy essential supplies or even travel to away sports games.

The victims included two men who were on a work trip to service a heat recovery system vital to a community’s water treatment plant, a retired teacher who was on a trip mentoring other teachers, and another person who was flying for a doctor’s appointment.

A medical transport jet with a child patient, her mother and four others aboard crashed into a Philadelphia neighborhood on Jan. 31, exploding in a fireball that engulfed several homes. The crash killed seven people, including all those aboard, and injured 19 others.

The Learjet 55 took off and then plummeted in a steep descent, crashing less than a minute after takeoff from the Northeast Philadelphia Airport. The plane hit the ground during a busy Friday evening less than 3 miles (5 kilometers) from the airport, leaving a crash scene of at least four blocks.

A father who was inside his car when the small plane crashed was among those killed.

The plane operated by Jet Rescue Air Ambulance was on its way to Mexico, returning the child, who had spent months in treatment at Shriners Children’s Philadelphia hospital.

Jet Rescue is based in Mexico and has operations both there and in the U.S.

A midair collision between an Army helicopter and an American Airlines flight about to land at Washington's Ronald Reagan National Airport on Jan. 29 killed all 67 people aboard the two aircraft. It was the country’s deadliest aviation disaster since 2001.

The regional jet out of Wichita, Kansas, was carrying 60 passengers and four crew and preparing to land when the helicopter apparently flew into its path, causing a collision that sent both aircraft into the icy waters of the Potomac River.

The UH-60 Black Hawk, based at Fort Belvoir, Virginia, was on a training exercise and carried three soldiers.

Among those killed were members of the Skating Club of Boston who were returning from a development camp that followed the 2025 U.S. Figure Skating Championships in Wichita.

The victims also included a group of hunters returning from a guided trip in Kansas, four members of a steamfitters’ local union in suburban Maryland, nine students and parents from Fairfax County, Virginia, schools and two Chinese nationals.

KYIV, Ukraine (AP) — Ukraine denied Moscow's claims that a Ukrainian drone struck the Russian-controlled Zaporizhzhia nuclear plant, as Kyiv on Sunday launched fresh strikes overnight on Russian energy sites.

Ukraine’s General Staff said Ukrainian drones struck the Saratov oil refinery in southwestern Russia, causing a large-scale fire. It said the extent of the damage was being clarified, and claimed the refinery has been supplying Moscow’s war effort.

The refinery belongs to Russia’s state oil enterprise, Rosneft. Local Russian Gov. Roman Busargin, said Ukrainian drones had damaged civilian infrastructure, but did not immediately give details. Astra, an independent Russian news channel, said an oil refinery was on fire in the city of Saratov.

Ukraine has stepped up its attacks on Russia’s oil and gas facilities in recent months, arguing the energy sector both funds and directly fuels Moscow’s more than 4-year-old invasion.

“Tonight, our soldiers applied Ukraine’s long-range sanctions against an oil refinery in Saratov, Russia — approximately 700 kilometers (435 miles) from the front line. A significant achievement,” Ukrainian President Volodymyr Zelenskyy wrote on social media later on Sunday.

Drone debris also set fire to a fuel depot in Russia’s southwestern Rostov region, which borders Russian-occupied eastern Ukraine, Gov. Yuriy Slyusar reported on Telegram on Sunday. He said residents of nearby homes were evacuated.

Ukraine's General Staff on Sunday confirmed its forces were behind the strike on the facility in the town of Matveev Kurgan. Local authorities said a drone strike on the depot had caused a large-scale fire across a wide area.

According to its General Staff, Ukraine ​also struck the Lazarevo pumping station in Russia's Kirov region northeast of Moscow, more than 1,200 kilometers (745 miles) from Ukrainian-controlled land. The station helps ship Russian oil ​from Siberia to Belarus.

Regional Gov. Alexander Sokolov said drones had hit ​a facility in the Kirov region, without giving further details.

Kyiv denied a Russian claim that a Ukrainian drone struck the Zaporizhzhia nuclear plant, Europe’s largest.

Russia’s state nuclear energy company, Rosatom, said on Saturday that the drone exploded after tearing a hole in the wall of a turbine hall. Rosatom’s CEO Alexei Likhachev accused Ukraine of a “deliberate” attack.

“This afternoon, a Ukrainian kamikaze combat drone struck the turbine hall building of Power Unit No. 6, resulting in a detonation,” Likhachev said. He added there was no damage to main equipment.

Ukraine’s military said it did not target or strike the plant, and described the Russian claim as “yet another propaganda ploy.” A military statement said that it adheres to international humanitarian law and is aware of the "consequences of any actions targeting nuclear facilities.”

“Along the relevant section of the front line, there was no active fighting at the time of the incident, and no weapons were used,” it added.

Rafael Grossi, head of the International Atomic Energy Agency, voiced “serious concern” in a post on X following the incident.

The IAEA said in a statement Sunday that its inspectors “observed damage to the exterior of a turbine building” that was “consistent with the impact of the drone.” It gave no details of where the drone may have come from, but said radiation levels at the site remained normal.

“During a site walk down, the team saw damage to a metal access hatch located several levels up in the building, as well as a few pieces of debris and burned optical fiber remains on the ground," the agency said in a post on X. It added its inspectors had requested access to the inside of the turbine hall for further examination.

Russian forces captured the Zaporizhzhia plant in the early weeks of the war, and it remains close to the front lines in the southern Zaporizhzhia region, one of four Russia has formally annexed despite lacking full military control or international recognition for its actions.

The nuclear plant has repeatedly come under fire since Russia's full-scale invasion in February 2022, sparking fears of a nuclear accident. Moscow and Kyiv have blamed each other for targeting the plant.

Elsewhere, Ukraine’s air force said Sunday that it had shot down 212 of 299 drones launched by Russia overnight. It said 14 drones had reached their targets, while drone debris fell in five locations.

A truck driver died early on Sunday as drones hit a parking lot in Ukraine's northern Chernihiv region, according to local administration head Vyacheslav Chaus.

Russian drones struck the city of Dnipro and an oil refinery in Ukraine’s Rivne region, causing fires, authorities said. No one was injured in either location, Ukrainian officials later reported.
