I could hear the first craft going over but all I could see was blue sky where the sound was coming from. Then it appeared for only one second like a faded bluish gray image that looked like a military aircraft. Minutes later the second incident involved a military jet releasing a chemtrail for a short distance then going straight overhead. Two bright orange flares lit up on the wings and were released. Two faded bluish gray craft that looked more like long speed boats suddenly appeared in a clear blue sky and moved slowly around the still burning flares then disappeared again. All that was left was a smoke trail from the flares in a blue sky. There was heavy military aircraft activity in the area all day. Several aircraft released chemtrails during the day. My location was about ten miles East of the Susitna Lodge on the Denali Hwy.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
