Once a rocket was launched, which had the following feature: the first few seconds after the launch, it flew strictly vertically, and then the tangage program began to be worked out, i.e. The rocket was targeting. At that time, the launch was successful, the rocket left the launch table, beautifully left, but... the program of the twist on the tangage was not included! The rocket with the reef went to the zenith, the commission thoughtfully followed it through the eyes and then it came to the smartest that after burning out the fuel, the rocket together with the warhead will return to the start! Without speaking, the members of the commission looked around and, like running camels, broke with wild speed in different directions along the barks, stirring up clouds of sand.
It is said that after that the following fourth was born:
Smoke, falling, a rocket
She ran away from the calculation...
Whoever has ever seen this,
That $X will come to the rocket!
