'Recently, a pilot sent www.data4science.net several images of a plane which is clearly rigged for aerial chemtrail or biological spraying taxiing on the ground at an airport in Canada. After studying and researching the plane images and origin, I feel they are authentic. Why do I suggest the plane might be used for biological spraying? Previously released photos of acknowledged experimental spray planes built for NASA had massive concentric rings mounted on the rear tail of the plane.'
