Certainly if he had turned, upping his wing-stall speed he would have entered an incipient spin, then a full spin. The Call air cruised at about 100-120 MPH and with its short wing span had a higher stall speed than say a J-3 Cub, Aeronca or Taylorcraft [the latter, a high wing was the plane they used to represent Arnold's plane in the movie UFO. Real attention to detail there]. As search planes go, the Callair was a poor choice. His wings would have covered hundreds of square miles below him. Having been [and still am] a volunteer search and rescue pilot, I can atest to just how hard it is to spot a downed aircraft at high altitudes [or low for that matter. Usually you find them due to other clues such as tree tops being clipped off, a swath being cut into low brush or the trees, or the plane's own reflectivity. In Arnold's case he was likely looking for an aircraft that could have been at a varity of altitudes and which likely buried itself in the snow or was covered over by same. We search with four aboard [pilot, navigator and two spotters in the back seat] using high wing aircraft [C-172s, 182s or 180s, etc. all of which have 36 foot wing spans] at 700-1000 feet with flaps on, cruising at about 90 miles per hour to prevent a wing stall during turns. Even then they are shallow turns. Arnold's Callair had a wing span of about 26 feet and no flaps and were low as I mentioned before. I doubt if he was flying at a speed of any less than 90 MPH or perhaps even 100. It would make no difference at the altitude he was searching. This would have had him looking ahead of the left wing and down with the occassional glance behind his wing in case reflectivity might have indicated the crash site due the angle change. I don't know if any of this helps put your head in Arnold's Callair James. It's just like anything else though, there are many misconceptions about piloting an airplane, more than a few of which I have mentioned during this thread. You mentioned that your friend sped away from the peligans at 80 MPH. If that was a pure sail plane the only way he could have done that was by diving away from them to gain speed, unless it was a motor-glider. It doesn't say. Your glider friend also mentions visibility factors, such as haze. All true, but Arnold is on record as saying it was a beautiful day for flying with the air very stable and clear. I've been up on days like that and it is a joy to behold. You can see 75 miles-plus once you get up to a mile or so. Whenever you get air that clear, it's because its very stable and cold with no convection currents to whip dust, smoke and other pollutants into the upper atmosphere. Despite this being the air age, the general publics knowledge about flying is very poor with many misconceptions fostered by the entertainment industry. Hope this helps. Don Ledger
