POTUS @ Stanford

We saw him fly in via helicopter on Wednesday evening and he's been stopping around the Bay Area since then with a landing on Chrissy Field as well.  Those Osprey helicopters look and sound impressive close up! Too bad the students weren't around this time.

Thank you. I saw one on TV when they were discussing Obama's arrival and I had no idea what it was.

P.S. I took a course on Russian History from Mike McFaul; one of my favorite professors.

To be exact, on Wednesday (correction: Thursday) Obama flew into Moffett field on Air Force One, then went by helicopter (Marine One) up to Crissy Field, then by ground to his hotel/restaurant. The Osprey tilt rotor aircraft (they are not true helicopters) are indeed impressive, but at least as of April the POTUS did not fly on them due to safety concerns (unlike helicopters, if the engines stop they can't make a soft landing).

Would you believe . . . I wrote that post from the other side of the International Date Line?
Would you believe . . . I was referring to a different visit by Obama?
Would you believe . . . I wrote Thursday but the autocorrect function stupidly changed it?

It was very possible you saw the helicopters and Ospreys on Wednesday as they did a test flight prior to Obama arriving in the Bay Area. I saw them on Wednesday as well and thought my calendar was off. It was only on Thursday when I saw the helicopters taking the same flight path at the same time, did I realize they were doing a test run the day before.

How "soft" is a soft landing when the helicopter engine fails? I'm guessing not feather-bed soft.

you're right that "soft" is probably misleading, but apparently it (autorotation) makes "landing" soft enough to make a crash more survivable.
from supreme authority Wikipedia:Â "In normal powered helicopter flight, air is drawn into the main rotor system from above and exhausted downward, but during autorotation, air moves up into the rotor system from below as the helicopter descends. Autorotation is permitted mechanically because of both a freewheeling unit, which allows the main rotor to continue turning even if the engine is not running, as well as aerodynamic forces of relative wind maintaining rotor speed. It is the means by which a helicopter can land safely in the event of complete engine failure. Consequently, all single-engine helicopters must demonstrate this capability to obtain a type certificate.[5]"
