sister ans i were sliding in the snow;when this egg object landed;

sister and i were slideing in the snow. on the back road in danville n.h.when this egg like object landed; about 1/4 mile away.it stayed down for about 15 mins.came up and hovered above the trees for 5 more min,then it shot up straight up so fast like a flash. 
then a airforce fighter plane flew over so close we could see the pilot and his gear.but by then the object was long gone. 
to this day iwill never forget that; it is forged in my mind for ever
