it was christmas night i just got a telescope for christmas wanted to set it up and show my son planet in sky not sure if it was mars or saturn i was having trouble zooming in so my brother in law tried he got it better than me but still couldnt see very well it was very clear out that night dont remeber seeing moon either all the sudden we were looking up at planet and talking and boom this light just appered to the south east of planet it was very high in the sky we both said there is another planet and all the sudden it started moving to the south at high rate of speed only lasted about 5 sec. was very weird i am familiar with military aircraft air dover airbase 30miles away this was not an airplane nor planet nor satilite i have seen satilites in the sky bofore this light appered like a bright planet but one minute ther was nothing the next it was there and then flew off
