Bullet shaped ray/light streaks span across sky of glowing white

was called over to window by my dad who was not in mood for talking and was falling asleep late in a work site cabin of him and i. forested in, barely any folk that live near, over the lake i see a bullet shaped glow hovering in the night sky with white rays increasing in size trailing, beaming outward. HUGE GLOWING STREAKS ACROSS ENTIRE SKY TOWARD THE BACK. Bullet/triangle thing moves considerably and so smooth for aircraft and then boom disappears. All the light that at this point covered half the entire sky just disappeared.
