Re: [Phys-l] Electron vs. Alpha particle...



I was reading last night about Tibbets and his crew training for their bomb runs. They needed to be about 8 miles (for estimated r^-2 dissipation) from the blast center by the time the expected shock wave reached the plane so that it wouldn't throw the plane into an uncontrollable condition. The problem was that with normal airspeed they would only be about 4 miles away, (plus they wanted to turn back toward base) by the time the bomb fell from 31000 to 2000 feet. To get the extra airspeed, they did a diving turn, changing course by 155 degrees during the turn. That must have been some kind of exciting ride.

You can also slow the aircraft, pull fully back on the yoke, and go into a deep stall with a delayed recovery. It's heartstopping, but the view of the ground is spectacular.

Pilots of light aircraft can look down by applying aileron to roll
and canceling the coupled yaw which would turn the airplane,
by commanding adverse yaw with the rudder and
then increasing pitch to hold altitude.

Lets one know how little I remember from the ONE time I flew an aeroplane (paper piper).

Please elucidate.

bc got taken over because "he" wandered too much.
