FAA grounds 171 Boeing planes after mid-air blowout on Alaska Airlines jet

The US airline regulator has ordered the grounding of some Boeing 737 Max 9 jets after part of one plane fell off during an Alaska Airlines flight.
The Federal Aviation Administration (FAA) said the inspections would affect 171 planes.
On Friday the Alaska Airlines flight had to make an emergency landing after take-off from the US state of Oregon.
United Airlines says it has carried out the inspections required by the FAA on some of its 79 Boeing 737 Max 9 planes.
Removing some of the aircraft from service is expected to cause about 60 cancellations on Saturday, the airline said in a statement.
Earlier, the FAA said it would "order the temporary grounding of certain Boeing 737 Max 9 aircraft operated by US airlines or in US territory".
Required inspections will take around four to eight hours per aircraft, it said.
The UK's Civil Aviation Authority (CAA) confirmed that there were no UK-registered 737 Max 9 aircraft.
"We have written to non-UK and foreign permit carriers to ask inspections have been undertaken prior to operation in UK airspace," they wrote on X, formerly Twitter.
In Friday's incident, the Alaska Airlines flight from Portland, Oregon to Ontario, California, had reached 16,000ft (4,876m) when it began its emergency descent, according to flight tracking data.
The airline, carrying 177 passengers and crew, landed safely back in Portland.
Images sent to news outlets showed the night sky visible through the gap in the fuselage, with insulation material and other debris also seen.
There were no immediate indications of the cause of the apparent structural failure, nor any reports of injuries.
Passenger Evan Smith said: "There was a really loud bang towards the left rear of the plane and a woosh noise - and all the air masks dropped.
"They said there was a kid in that row who had his shirt sucked off him and out of the plane and his mother was holding onto him to make sure he didn't go with it."
In an audio clip, the pilot can be heard talking to air traffic control requesting a diversion.
"We are an emergency," she said. "We are depressurised, we do need to return back."
According to photographs, the affected area was in the back third of the plane, behind the wing and engines.
The section of fuselage involved appears to be an area that can be used as an additional emergency exit door by some operators, but not by Alaska.
Terry Tozer, a former airline pilot who has written extensively on aviation safety, said the section should have been bolted into place if it was not being used as an emergency exit.
He told the BBC News Channel that the passengers would not have been able to tell the area was not a normal window from inside the cabin.
While the loss of this section would probably not have affected how the aircraft flew, Mr Tozer added, there would have been a "huge risk" to anyone sitting nearby.
"Fortunately, there was nobody sitting in that window seat. Had they been unbelted, they may have well been sucked out," he said.
Announcing the initial grounding of 65 planes, Alaska Airlines' CEO Ben Minicucci said: "Each aircraft will be returned to service only after completion of full maintenance and safety inspections."
