Few days ago, while my son is taking his siesta time. I decided to get some leaves for the guinea pigs when I saw the first broken contrail. It seemed to be there for a moment already.I remember aircrafts long ago may form contrails but it disappears while the aircraft is moving but this time it's different, contrails seemed to be staying longer up there.
Suddenly, another contrail from an aircraft formed.
Lastly, when the two contrails seemed to have vanished already, another aircraft formed a contrail. This is something I seldom see, three contrails, one after another.
