Answer:
It is likely that the government of the USSR would believe it necessary to state to the government of the US that a USSR military aircraft and a US military aircraft were engaged in a skirmish over Sverdlovsk, and that a US military aircraft, trespassing in Soviet airspace, was shot down over Sverdlovsk. This would be a significant event and could potentially lead to tensions and conflict between the two countries. It is important for governments to communicate and address incidents of this nature in a transparent and peaceful manner in order to prevent escalation and maintain international relations.
