    Yes, he seems to have been involved in all sorts of interesting projects. Did 
    you come across the descriptions of his experiments with a bubble sextant 
    aboard the airship R-33? Apparently his results were comparable in accuracy 
    to land-based observations with the same instrument: LOPs accurate to about 
    +/-2 miles.
