object moving high in the sky and emitting two flashes, then changed color to dark orangewas first looking like a white light of a plane, not flashing, approx. 30'000 feet high ( although very difficult to say the altitude) then emitted two flashes (like sunlight reflecting) but the flashes were 10 times bigger at least than the object. Ouah ! then moved much much faster ( faster than you would see an airplane move). After about 35 to 40 sec (here also difficult to tell the amount of seconds elapsed, didn't look at my watch, you only want to follow the thing) the thing changed from white to yellow dark, made a kind of half turn, like a half loop almost not complete. then the light faded. Great sight indeed. when the thing faded was located North, nearby or in the charriot. (I have had doubt on myself some half an hour later, If I had been victim of an hallucination. - even thought I turned to be a fool.. gosh !!)
