That I know of, I am not the only USAF Nav that shot Venus-Day observations. I think the USN P-2Vs were doing this too. Any USN navs out here? The Venus-Day observation was not real common but not too hard to do with a D-1 Kollsman periscopic sextant. Venus on a day shot appeared as a "diamond dot" in the bright sky:was there and depending on the filter you introduced:worked well as far as I remember. I used celestial almost exclusively in my south Pacific flights. Last week in a discussion with the only Lockheed Electra, L-12A N18137, fliers I know of, Captain Curtis Walter and Ruth Richter Holden (who's dad was a founder of TWA and greatly responsible for MATS) I was told, "Looking out of the cockpit of the Electra was like looking out a mail (box) slot." Not quite a ringing endorcement of the being able to see out well. On top of that I was told the T.O. and Approach angles were terrible as far as seeing forward. Having flown tail draggers I know there is a work around:however in either case I was not trying to shoot a on-the-horizon celestial shot. Too fun. We might ask these two Electra fliers to record their testimony about the Electra here. Looking at you model picture:it is like the one I posted. I can only guess what drawings the makers used to get them right so to speak. Nice models though. Has anyone got a set of Lockheed technical drawings of L-10AE NR 16020? As an aeroengineer I'd like to get a set to research. With specs and station numbers. Is the forward section on the Electra's alike? Anyone know a Lockheed production engineering historian? We need technical data here. Ron Barrett, President Air Force Navigators Observers Association (AFNOA) --- On Tue, 12/1/09, Gary LaPook <glapook@pacbell.net> wrote:
