I can fly way more than twice as high. Because I just went for a flight in my boss's plane! And we didn't crash or anything. We took off from Palo Alto airport, flew up the peninsula, over the city and Marin, then back on down. I got to listen to all the tower and pilot people T(ango)A(lpha)L(ima)K(ilo) over the radio.
Here's the view as we were coming in from the Pacific and about to pass over the Golden Gate Bridge. That's the wing in the lower right hand corner. Yeah!
