Europe has implemented the same kind of rules recently, but the ex-Soviet states have not - hence the deaths.
Actually, the Soviet states do have rules.
The Su-27 crash is now a criminal investigation....
As Ukrainians prayed for the dead on a national day of mourning, Prosecutor-General Svyatoslav Pyskun said the pilots had been given a "wrong task" by their chiefs, who had flouted safety rules by allowing them to fly over the crowd. He said four top military officials, including the ex-Soviet state's air force commander, were in detention cells awaiting a court decision on whether to continue to hold them during an investigation into their "serious errors". "It was negligence, military negligence...it was a crime committed by the military," he told a news conference, adding it was so far unknown why the plane had crashed. "There are also signs that there were criminal acts committed by the pilots," he said. Most analysts have said spectators should not have been allowed to sit or stand under the flight path of planes taking part in the air show. They say the twin-engined jet that crashed was flying too low to complete a rolling turn.
If rules are broken, you can't say that rules aren't there, but that those breaking the rules are responsible. Can happen anywhere; America, Europe or CIS
