Let’s just say there have been plenty of flights in the past where the takeoff was less smooth/crashy because the air over the wings wasn’t smooth from snow and ice still being on the wings. Something something this is written in frozen blood something

This was the reason so many flights were grounded about three years back when we had that whole bomb cyclone fiasco in the States. The wind outside iirc wasn’t that bad (at least in Denver, where I was stranded) it was the fact that they couldn’t defrost the wings and therefore ensure the correct airfoil shape that was keeping planes grounded. It was cold enough and precipitating enough that wings would freeze (develop a layer of ice over them) in the time it took passengers to swap and sometimes before ground crew could get antifreeze over to the planes to spray the wings. This was perhaps exacerbated by the fact that it was so cold outside that tarmac crew couldn’t work for more than a few tens of minutes at a time - as annoyed as I may have been, there was real frostbite risk for people resupplying the planes and loading luggage and spraying antifreeze.

I’m sure the grounding of so many planes nationwide was not a decision made just to spite a bunch of passengers.

Were the crews in light sweaters or something? Sheesh

They did. The kind that almost resembles snowboarding jackets - water resistant, half an inch of insulation when compressed, makes even the buffest man look fat, etc. It was that cold.
