And I know what celestial navigation is. Could a US marine explain how catapults are tuned musically by Romans for symmetrical power? Is that part of the training?
The point was why should you know that celestial navigation existed for aircraft flights. You had no clue. Then instead of researching it in that thread you made up some willy-nilly story that celestial navigation was never used on aircraft. I have no problems with you not being trained on it - as I realize that U.S. Marines rarely use catapults. I stated that Marines knew of their existence - which you did not and pulled a Tom Bishop.
I had every clue.
And how about when the FMS loses its functionality?
I told you before not to joke about that. 
Well an answer would be nice.
Holding back the tears, one announces on the radio "Mayday, Mayday Mayday! Speedbird one fife two is a 737 from Heathrow to Geneva. Currently fifty miles south of Paris, flight level tree fife zero. FMS is defective, request vectors to nearest diversion."
To which one would expect
"God alive man, we are going to get you down! Hang in there! Turn left heading zero niner fife and descend flight level two hundred. We will clear all traffic and give you a straight in approach for Lyon Airport."
To which one should gratefully reply
"Thank you so much. We are all counting on you up here. "
The first officer is then expected to allow the Captain to use the toilet first.

Yes they even had automated periscope sextants for aircraft
What an expert. I don't know why they bother training us when people like Berny know it all already.
Actually I didn't know how automated they were until I looked more into it during the thread when you argued celsestial navigation was only used to find the north star.
That is probably the last time I follow Tom Bishop into a thread that he subsequently may abandon.
I am having a hard time in following you guys, has the thread derailed?
What was the original topic anyhow?
Stephen Hawking; puppet for the conspiracy.

Wow.
Marines using a catapult.
Its probably exactly what they do on team building exercises, but I am speculating.
