    … is the increase in lift force, decrease in aerodynamic drag when a fixed wing aircraft is in close proximity to a fixed surface which gives the sensation of floating … it also applies equally to our winged friends when they have their wings set and within their wingspan to the surface. This Great Blue Heron with wings fixed and in this same body position maintained approximately this altitude for more than a hundred feet as he glided over the dry pond bed before rotating and planting his feet on the ground. It is a neat thing to watch and even better when I capture the event to share with you.

    You can read more about this phenomenon at: https://en.wikipedia.org/wiki/Ground_effect_(aerodynamics) One of the things I do not like about ground effect is landing on R21 at Sedona where the ground is receding from you at the rate of 2’ per 100’as you travel down the runway and the ground effect, especially in a glider, tends to keep you off the runway and on a sunny day the black runway is throwing lift as it is heated by the sun … somedays it provides a wonderment if you are really going to touch down … you always do, just a requirement for patience until it settles.

    A very good week underway … hope yours is too … smile, we are here and aware … for now.

    Cheers

    At nightfall…though I know I shall sometime no more
    Open my eyes to the light or day, I am one who looks at stars when
    Unchained from the work-bench at Nightfall.
    They are a sign that I am not ephemeral,
    Not you, nor you, whoever you are.
    The dawn comes and the dark and the sign sparkling in the brooding night,
    Forever and forever.

    Analyzing City’s Legal Right to
    Ban OHVs on Public Roads

    By Tommy Acosta
    Mea Culpa! Mea Culpa! Mea Maxima Culpa! I screwed up. Blew it. Totally made a fool of myself. Missed the boat. I am talking about my editorial on the OHV fight, No Legal Traction on OHVs. I assumed that it was ADOT that would make a decision on whether the city could legally ban off road vehicles from our public roads like S.R. 89A and S.R. 179. Man was I off. ADOT has nothing to do with allowing or disallowing the city to do so. ADOT’s response to me when I asked them to clarify their position, was curt and to the point. “ADOT designs, builds and maintains the state highway system,” I was told. “It is not our place to offer an opinion on how state law might apply in this matter.” It was a totally “duh” moment for me when I realized that that the decision or judgement on the OHV ordinance, would involve the state and not ADOT. Chagrinned I stand. The crux of the matter then is whether the city can effectively use a number of standing state laws that can be interpreted to determine whether the city can legally ban the vehicles or not.
