Runway Mishap At Toronto
Delta CRJ900 is flipped on the runway at Toronto Pearson Airport.

New York Post reporting:
Delta Air Lines flight upside-down after crash leaves multiple injured at Toronto Pearson International Airport

A Delta Air Lines flight went belly-up after crashing at Toronto Pearson International Airport on Monday.

Emergency crews confirmed they were responding to an “incident” at the airport and that all passengers and crew members had been accounted for.

Delta Flight 4819, which took off from Minneapolis about 11:47 a.m., appears flipped on its back on a snowy runway, according to photos and video posted online.

At least eight people have been reported injured so far, according to CP24, but the severity of their injuries could not be immediately confirmed.

The plane is a Mitsubishi CRJ-900LR, according to flight records.

Emergency services attending reported plane crash in Toronto
Video of the aircraft actually landing has surfaced.
ADS-B data posted at PPRuNe shows a pretty much normal stabilised approach until just before touchdown.

The video shows the aircraft coming in to land normally, but instead of flaring, it continued to fly into the ground, landing very, very hard.
I suspect the impact was sufficient to cause the right wing to break off, and the forward momentum & velocity of the remainder of the aircraft was such that the left wing (still attached) provided lift causing the aircraft to roll over as it slid along the runway.


Wild speculation- either
1 windshear or a down draft right as the plane was at the point of flaring. It takes a second or two to realise what is happening and react. It takes a few seconds for the engines to spool up after being commanded to increase power (smaller engines less time due to less mass & inertia, but still a significant delay from when the throttles are moved to when the engines respond).
Given the low altitude, the aircraft had probably hit the ground before the pilot could react, let alone the engines spool up for more power.
2 the pilot misjudged their height above ground level and left the flare too late and just flew it into the ground.

Very interesting. Looks like the pilot had a bit of right wing low a few frames before touchdown. Looks like the right main failed*, right wing struck the ground**, both engine compressors stalled (snow ingestion?) and then all heck broke lose.

With both pilots and both black boxes and the entire airframe they will get a definitive conclusion.

*not locked, overload or impact with something other than the runway. TBD.

**breaking or shearing the spar and separating from the fuselage.

Note I haven't seen any photos of the separated wing. It is possible that the spar sheared first and the landing gear played no part. Again pending microscopic inspection.

If you want to discuss the politics behind and around this tragic helicopter vs. aircraft crash there's a place to do so:

A much better video of the crash from a different angle.

https://www.instagram.com/reel/DGNgCI0MC68/?igsh=czJ4dHlrdnIxbTM5


I've watched it least a dozen times- every thing looks good, then it just starts to drop faster, lands hard, right side first, right wing hits the ground and breaks off, slides for a bit, then rolls over as it continues to slide...

The tally keeps on climbing.

Horror images show a plane left in smouldering pieces after a mid-air crash that has left two people dead in what is the seventh air disaster in three weeks.

Two people are dead after two planes collided mid-air at an airport in Arizona in the seventh air disaster in the US in just three weeks.

Shocking photos show the smouldering crash site after the planes slammed into each other at the Marana Regional Airport outside Tucson, Arizona, on Wednesday, the US Sun reports.

First responders raced to the airport at 8.30am (local time) after reports of a downed aircraft.

They quickly determined that a Cessna 172S and Lancair 360 MK II had collided mid-air......

.....The airspace around the airport is uncontrolled, meaning there’s no air traffic control tower.

A tower was supposed to be installed by the end of 2024 but the new deadline for installation is 2029 due to delays during the pandemic, according to local reports. Pilots flying in uncontrolled fields are expected to announce their position to other pilots who are at or near the airport....

This looks like a RUNWAY INCURSION... the landing aircraft has to pull-up and abort landing.
From The Chicago Sun-Times ...
Southwest Airlines pilot's fast action averts disaster at Midway Airport (Chicago ): 'Uh, how’d that happen?'
A Southwest Airlines jet attempting to land at Midway Airport nearly crashed with a business jet that had crossed into its path Tuesday morning, according to the Federal Aviation Administration.

Officials said the incident occurred shortly before 9 a.m., when Southwest Airlines Flight 2504 from Omaha, Nebraska, was attempting to land.

In a video of the incident posted to social media (also embedded in article), the Southwest flight is seen close to touching down, then pulling up as a smaller business jet taxis across its path. The Southwest flight returned to the air before later landing safely and “without incident,” according to an emailed statement from Southwest Airlines.

"Without incident"
I bet there was a verbal character reference given for the crew of the business jet by the SW crew.

Well that'll interrupt your journey.

Eurostar trains stopped after unexploded WWII bomb found at Paris station.

Eurostar trains in a Paris train station have been cancelled following the discovery of an unexploded World War II bomb.

The bomb was found near train tracks serving the French capital's busy Gare du Nord station, triggering cancellations and leaving travellers heading to and from Paris stranded.

Commuters have been urged to postpone their trips, with only limited services resuming throughout the day, French Transport Minister Philippe Tabarot said.

Mr Tabarot said traffic would be ''strongly disrupted'' throughout the day with only limited service resuming in the afternoon.

France's national train operator SNCF said in a statement that traffic was stopped at the request of police......

That's the typical British 'looking through the wrong end of the telescope' viewpoint - "small bomb on the tracks, Europe cut off".

The bomb was actually about a mile north of what is being reported as the busiest station in Europe. The Gare du Nord services Paris suburban trains, regional services to the channel ports, old-fashioned express trains to northern French regional cities, domestic French TGV high-speed services [we can't even agree on HS2], international high-speed services to Belgium, the Netherlands, Germany (with more to come), and a tiny, tiny number of Eurostar services to/from London. No other British city has a direct link to any part of Europe.

It's pitiful, but the headline writers love it.

But the Eurostar trains from St Pancras to Amsterdam and Brussels "hang a left" at Lille to avoid Paris by a safe distance. (Paris is my least liked French city and so is well worth avoiding if at all possible.)

Hah... I've got the same sentiment: these impatient Parisians tend to answer annoyed in English if your accent clearly reveals a foreigner with imperfect French. Snooty people... How different everywhere else...

Another comes crashing down.

A plane has crashed in the carpark of a retirement community in Pennsylvania, with reports at least five passengers were on board the aircraft.

According to local media, the crash happened at Brethren Village in Lancaster County, Pennsylvania.

Shocking video has emerged showing the fiery aftermath of the small plane crash, with vision showing the aircraft in a fireball wreckage in the carpark with black smoke billowing from the scene.

Local police said the plane “went down” on Sunday (Monday AEDT) and emergency crews are responding. No official toll on injuries has been confirmed, however CNN media affiliate WGAL confirmed multiple ambulances were on the scene. The Federal Aviation Administration said five people were on board the single-engine Beechcraft Bonanza, however their condition remains unknown as each have been taken to hospital.....

Meanwhile at sea.

More than 30 people have been rescued after a cargo ship collided with a US oil tanker carrying military jet fuel off the British coast.

A major rescue operation has taken place after a collision between an oil tanker and a cargo ship in the North Sea, off the UK coast, which sparked a huge blaze.

One person was taken to hospital and 36 other mariners were rescued. No one is thought to be unaccounted for from either vessel.

Jet fuel is spilling into the North Sea, however.

Swedish tanker company Stena Bulk confirmed it owned the oil tanker involved in the accident, adding that it was operated by Crowley, a US-based maritime company.

The oil tanker, the Stena Immaculate, is one of 10 worldwide which can supply the US armed forces with fuel in a conflict or national emergency. News agency Reuters reported the ship was on a short-term charter to the US Navy’s Military Sealift Command carrying jet fuel.....
