Good question. Out for maintenance or calibration? It was a CAVU day it appears so - questions remain - we’ll all know in a couple of weeks as soon as the MSM gets through playing the story with falsehoods of all sorts.
We might never know why that plane had to declare mayday. You know, why were there holes in the top of the fuselage? Why did the landing gear fail? Why did the tail shear off? Things like that.
I generally know enough to get by as someone that likes planes, but I don’t know that kind of terminology. I know things like IFR and VFR, angle of attack, attitude, stuff like that.
