940 hectopascal = 13.65 psi or 940 millibars.
Had forgotten about low air pressure and smaller planes.

Airline company Widerøe has in its almost 90 year history never experienced this kind of weather.
The past months have seen extraordinarily rough weather along the north Norwegian coast. Early this week came another extreme. The air pressure dropped to a level not seen in several decades.
According to the Norwegian meteorological institute, the air pressure across major parts of the region was below 940 hectopascal, a level that makes flying unsafe.
The Widerøe company that serves most of the regional routes put almost its whole aircraft fleet on the ground.
"Our smallest aircraft type Dash 100, 200 and 300 can not fly with pressure lower than 948 hectopascal,"
More than 2,000 passengers were affected by the weather conditions. Only on Tuesday afternoon did the pressure return to a level that allows aircraft to operate normally.
The low pressure also resulted in high waters levels along the Norwegian coast. In Tromsø, the north Norwegian town, the sea water was on Tuesday 354 cm higher than normal, the Meteorological Institute informs.

Global Depressurization! Raise taxes to create more millibars.
“not seen in several decades”
Guess it may be several decades before it’s seen again.
I hated the Dash 8. Like riding in a empty rolling soup can full of rocks.
Bernie Sanders will soon deliver a fiery speech about millibars and billibars...
It is the yearly “Storm of the Century.”
Trumps fault.
A figure of 870 millibar (25.69 in) was recorded on 12 Oct 1979 by the US Air Weather Service 483 km (300 miles) west of Guam in the Pacific Ocean in the eye of Super Typhoon Tip which involved wind speeds of 165 kts (305 km/h; 190 mph). Barometric pressure is the physical pressure exerted by all of the air above you.
Looks like 940 is a very low pressure. I am not sure if it is lower on average, near the tropics or near the poles.
“The low pressure also resulted in high waters levels along the Norwegian coast. In Tromsø, the north Norwegian town, the sea water was on Tuesday 354 cm higher than normal, the Meteorological Institute informs”
10 ft rise in sea level. Wow!
354 cm? That’s over 11 feet! (Maybe it was mm?)
So not enough air in the atmosphere to create pressure, or was it an abundance of mushroom spores?
Bring back the Zeppelin. Any pictures of the aircraft they’re using would add to this posting. Also mentioning speculation on wandering magnetic poles.
Hmm. The post on their twitter does say CM. And the photo looks like it - if that is the typical light pole post with a tall light.
There is one but thing, and one thing only, that could have caused this. Need I say it?

Is this like trying to fly at too high altitude?
If this keeps up, sooner or later we’re all going to die.
I wondered too, but centimeters is correct:

The boat dock photo shows at least several feet of water rise:
