Has anyone else witnessed something similar?

Approximately November 3rd 2016, Northern Alberta.

During the evening, my family and I were on our back deck when we watched five very large orange/red obs fly over the forest behind town in a V formation, they stopped over a particular area and began making odd maneuvers like above before rapidly accelerating in different directions and instantly vanishing, a blur of light and gone. I’d also like to mention that I’ve lived here for 19 years and have never seen anything like it before or since. The whole incident was less then 5mins, sadly I didn’t have my phone on my person and didn’t want to miss it looking for it. A friend of the family present did attempt to record it however has since lost the video, she said “it didn’t do it justice”.

I remember it was -2°c.

And in northern Alberta in the winter it’s dark at 3:30pm so the time was between 3-9 pm.
