It's -21 in my corner of flyover country today and I haven't heard a peep from my flying friends in the American southwest. I hope they're alright. As a humorist-friend (James Lileks) in this neck of the woods observed today, "it's -21, but it's a dry heat."
A question for aviators? Is this flying weather? I'm still a renter and the FBO won't release a plane in this weather, even if the engine did start. But for you owners, would you fly in this? It's a gorgeous sunny day and we presume the dense air would make any plane fly like a rocket.
As an RV builder, I wonder about the plexiglass canopy.
Oh, and I only put one heater box on the RV-7A project.
