Object viewed flying within wingspan of commercial aircraft

I was with a group of friends barbecuing just after 5pm yesterday evening. i was walking out into the open area because my friend was pointing to something in the sky. We then saw a small object flying dangerously close to a commercial airline. It looked to be metalic and spherical. The event lasted long enough for me to call out additional friends to see it as well. We did not get a picture of the event, however, i did snap a picture of a strange chemtrail left in the area of the event. Note that the craft was actually moving perpendicular to this trail though.
