Last night a Cirrus apparently flew straight into a mountain just north of Las Vegas. Lots of comments on COPA so far. The pilot was experienced, familiar with the area and a former ATC controller, which makes the accident hard to explain. One thing which struck someone - and me - as odd was that they would establish a floor to Class Bravo with a mountain sticking up into it: (The red circle is a TFR for the accident site) Maybe this is common, but it seems potentially dangerous to find a mountain right where you’d be maneuvering beneath a Class Bravo shelf. Tragic, regardless.
