The video shows three objects flying in formation across the Northamptonshire sky on 29 January 2018,
filmed with a full spectrum camera conversion in black and white mode with an infrared filter fitted to the lens.

The video starts with enhanced zoomed views, an unprocessed view and finally a view with heavy contrast and gamma adjustments as they became more difficult to see at this point without correction.

The objects don't appear to have wings, but do appear to be the same size, shape and point in the same direction as they pass over. There was no sound that I coud hear produced by these objects.

I was able to film them for about four minutes and appeared to change direction just before they dissapeared behind trees and houses.
They travelled roughly east to west and the wind direction was roughly from the NNW.
