This is about a very small percentage of the aircraft built under the Boeing 737 name, with a total of more than 170 aircraft worldwide. The FAA requires that prospective fliers conduct an investigation first.
Aviation company Boeing has been manufacturing the Boeing-737 since 1967. It is one of the most successful medium-haul airlines in the world. Of course more than 10,000 of these were sold in all variants.
KLM does not have a maximum of 9
Dutch (former) airlines such as Air Holland, KLM, Martinair and Transavia also fly or have flown with 737s from manufacturer Boeing.
As far as we know, KLM does not currently have any grounded Max 9 aircraft.
Early this morning (Dutch time), an Alaska Airlines Boeing 737 Max 9 lost part of its fuselage 35 minutes after takeoff from Portland, Oregon. The flight with 177 people on board landed safely.
The airline and regulator the Federal Aviation Administration say they are investigating exactly what happened. Aircraft maker Boeing said a team of experts was ready to help with the investigation.
The images show a large gap in the device, possibly due to the lack of an emergency door:
Two air disasters occurred in 2018 and 2019 with another type of Boeing 737 Max, the Max 8. In 2018, 189 people died on Lion Air flights in Indonesia. It is said that due to an error in the plane's software, the nose of the plane was pitched down and the pilots were unable to do anything.
Five months later, in March 2019, a disaster struck Ethiopia for the same reason. 149 people were killed.
