Booster, the rocket and tracks

For UFOs often take stages of rockets, parts of space ships burning in the atmosphere, the launches of various missile technology for military purposes, etc., and traces from them. They attract attention mostly in the dark, but in the day time have a greater aura of mystery.

Formation of the track of the launch vehicle occurs in the tropopause (the layer between the troposphere and stratosphere), which sharply reduced the vertical temperature gradient. The emergence of the so-called "jellyfish" influenced by water vapor, which are subject to enhanced condensation.

During the flight of the rockets, if their engines produce a sufficient amount of water vapor (all rocket engines, especially hydrogen and oxygen, producing only water vapor), contrails can occur in the upper atmosphere, where natural steam is not enough.

Engines solid-fuel rockets practically do not produce water vapor, but emit significant amount of particulate matter that also create a visible trail of smoke, but condensation by nature he is not.

Rockets family "Soyuz" equipped with side steps-boosters, which at the start included simultaneously with the second, Central stage. After the separation of the "marginalia", which together make up the first step, the Central continues to work. At the moment of separation of the side blocks away from the rockets family "Soyuz" occurs the famous "cross of the Queen", formed by separated and rotating "marginalia".
