At 00:45 my wife woke me up to tell me that her mother and her could see something in the sky that didn't look normal. we were visited her parents in cardston alberta. looking south in the sky we could see what looked like a helicopter. the flashing lights were similar to the twinkling of a star, but the object moved around a small area randomly. sometimes quickly otherwise slowly. that's why i thought it was a helicopter. it was hard to judge the distance. i could not see the structure of the object, but if it was a helicopter i should have been able to hear it. when i opened the window i could not hear anything from the object. i watched the object for about 1/2 an hour before finally going back to bed. i didn't have an explanation for it. i figured it was a drone, but why would someone hover in an area like that at night? if it was a helicopter why would it hover in a spot like that as well and use up all that fuel? my mother-in-law said she saw the same thing last week. my wife said she saw it again last night but she saw it with a beam coming down, so she's convinced it's a ufo. it was so hard to judge the distance. i wish i had a telescope so i could have had a better look at it. my wife and mother-in-law said they could see a second object that seemed to be tethered to the first.
