Airspeed over Altitude

In the helicopter world there are two kinds of take off profiles – altitude over airspeed where you are trying to clear an obstacle and airspeed over altitude where you gain flying speed before gaining any height.  It takes less power to do airspeed over altitude and as such that’s the preferred method, situation permitting.  It also makes sense for birds, though as quick as they are you seldom notice it.  Several doves in a nearby pine tree were being skittish and I was trying to get some pictures of them lighting and leaving the tree.  I caught this one almost by accident.  I could see him ready to leave and hit the shutter as he stretched out, catching him in his dive.  He’s a split second away from flapping his wings to level off.

Rainy Weather

The street outside our front door

We do have wet weather once in a while in the southwest.  Usually we get all of our rain for the year in a short period, aided by whatever storms happen to be moving our way from the Pacific Ocean.  By the time they get to us they’ve normally lost much of the energy they started with and break up into smaller thunderstorms moving north through the deserts.  This year hurricane Odile brought quite the storm our way.  As you can see from the aftermath we had a little street flooding.
