Flashgun tests...
I now realise that I neglected to mention ..... that my flashgun tests were done at mid-day .....................at the time of the crash , the sun was 29.6 degrees above the horizon , which equates to its position at mid-day at my home at this time of year....offering similar general light levels.......
......in case anyone wonders , any sun the crew saw would have been almost due west of them at 262 to 266 degrees True during the flight.......courtesy of US Navy tables....
