Could that also happen with a breath taken at the surface? What kind of
conditions would cause this? mike regish "John E. Carty" wrote in message ... "mike regish" wrote in message news:HNajb.136846$%h1.138365@sccrnsc02...

What kind of conditions would cause this? mike regish It can happen, from what I remember, anytime time you take a breath from 4 feet or more under the water and then ascend without exhaling. Took dive lessons in college for PE requirements, but that was a VERY long time ago :-) "John E. Carty" wrote in message ... "mike regish" wrote in message news:HNajb.136846$%h1.138365@sccrnsc02...

I always keep at least cruise power on when descending, until I descend low enough to maintain 2300/23", gradually enriching the mixture as I descand. I like to start descent 20-40 miles out, letting the speed increase, to make up for speed lost in climb. With normal cruise about 150 mph IAS at 10000, I can build up to about 170-180 MPH on descent (no worry, because redline is 230 MPH). That way, there is no spiralling down at destination or cylinder cooling. |

Not with my camera, the Olympus E-10 has a aiming dot, the focus is where the
dot is. My aiming point was actually downtown Phoenix but its so small your can't see it in the picture. Its actually just pretty hazy there from higher altitudes, SoCal is the same way. This picture I took over Oklahoma, I was at 8500 ft I think, it has the wing in it but the colors are good. I could touch it up with photo shop but it would take the natural look from it. http://216.158.136.80/newplane/trip/image5.html I actually prefer flying over the midwest area, flying was great, there are actually things to see, not like the desert, where it all starts to look the same.

We use an the Olympus E-10 digital camera for pictures. One thing I've found makes a HUGE difference with digital photography is to NOT get the wing in the picture. My digital autofocus usually locks onto the wing, and makes everything else in the background (which is what you're aiming at!) look fuzzy. Also, Photoshop does a much better job of adjusting color, brightness and contrast if you don't have a big, white wing in the picture. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Olympus makes some nice cameras.
The new E-20 I think it is, is suppose to be super crisp. We payed $1800 for the E-10 and it does everything we need so we didn't upgrade to the E-20. The E-10 has more functions then we actually use. "Peter R." wrote: Peter Duniho ) wrote: "Jay Honeck" wrote in message news:m4cjb.784881$uu5.136505@sccrnsc04...
