I was smoking in my back yard when i suddenly heard a humming noise. i have heard this noise before it happens sometimes before i go to bed. we'll the noise came back and and i saw what appeared to be the outline of something invisible above the trees. when i noticed the humming got very loud and then took off and the noise stopped and when i turned around i could see the ball of light leaving. i enjoyed it's beauty then decided to film it while it left into the clouds. an airplane passed by right after and so did a helicopter. i have video of all 3.
