    Dear Gary,

    Thanks for the page snippets here, (very) slightly I'm getting somewhere...

    My questions are:

    • why there is no HC stated on any LoP?
    • what are the short cross-marks along every LoP?

    I'd like to re-do all the LoPs myself, when exactly was the flight made in 1931, I'll be looking for Sun's ethemerides of the date.

    Warm regards,
    Tony
