Last night my wife and i saw 3 gliding red lights in a triangle formation. it lasted about 15 seconds. i live in great falls mt. there is a big airforce base and a air national guard, we see a lot of crazy jets and big planes as we live close to the airport. the odd thing about these red lights is they were close enough that we should have heard them, but it was silent and for a long time before and after there were no planes to be heard or seen and there is a constant stream of planes everyday. it was odd and i would like to know if there is anyone who could help me figure out what it was. i have been a casual conspiracy theorist for my whole life so this is like a dream come true. thank you and happy hunting
