Not an airplane contrail, not a rocket launch, nor a normal cloud! It’s left by a super meteor (a fireball), ionized gas in our atmosphere still glowing hot after the meteoroid object entered the atmosphere. The image shows the dragon-like “persistent meteor train” less than a minute after the meteor. While meteor trains generally last for seconds or few minutes, this was visible to unaided eyes for over half an hour, and detectable by the camera for about an hour. Click on the second photo to see this cloud half an hour later. See this development in a unique timelapse video. Read more about this on Phil Plait Bad Astronomy page. The scene is captured on the early morning of 2012 October 19 during the Orionid meteor shower, from a lake in northern Maine, USA.
