    Not exactly "archeology," CN still works in flight. For example, on August 30, 1978 I departed CYYT, Torbay, Newfoundland at 0309Z in a Cessna 172,
    N739PY and landed at LPAZ, Santa Maria, Azores at 1655 Z. Shot Rigel at 055530Z, Hs=15-17 and Capella at 060522Z, Hs=51-45  for a 0600Z fix. A 0710Z fix was determined by shooting Sirius at 070800Z at Hs of 08-15 and Pollux at 071130Z with a Hs of 29-36. I shot a sun line at 1103 Z and crossed it with a radio bearing on the Flores radio beacon, "FLO", 270 khz, for a fix 230 NM from Flores, the first island in the chain, which, if I remember correctly, is about 1050 nautical miles from Newfoundland, then about another 350 N.M. to LPAZ. Sept.1, 1978 I continued from LPAZ to LPPR, Porto Portugal about 800 N.M. and 7.5 flying hours. That leg was a piece of cake, it's hard to miss Europe. Then eventually I delivered that plane to the dealer in Brussels.

    I had the chance to step into Gary website on celestial air navigation, my hat off, for the content and the clear explanation of the air navigation approach to CN. While in marine navigation, the art of CN is, sometime and wrongly, considered obsolete, in air navigation we are already in the archeology area.
    I have a collection of books and instruments on air navigation dating back to the 1917 and always been fascinated by air navigation including the celestial components.
    Two years ago, I completed a 1,000 miles ferry of a Stearman from Sweden to Central Italy, my navigator relied exclusively on GPS for the ride, I did my log and always checked the GPS reading against my DR predictions and pilotage periodic verification of the actual position, the GPD did let us down few times, the best of then was during the crossing of the North Sea between Sweden and Germany, it is a peculiar moment when you don't see land on the 360 and the warning "no signal" comes about........
    Well done Gary.

    Following is a pic of the Sweden-Germany crossing, with not auspicious clouds at the sea horizon ( not forecasted by the Met guys as well)
