RBC Radio posted what it claimed was an audio recording of an Il-22 crew radioing to controllers in Anapa. “Urgently requesting ambulance and fire crew,” the crew said.

Ukrainian air-defenses reportedly shot down two of the Russian air force’s rarest and most valuable command aircraft on Sunday: a Beriev A-50 radar early-warning plane and an Ilyushin Il-22 airborne command post.

Ukrainian media has cited government officials confirming the purported shoot-downs, but there’s little hard evidence of the incidents.

Ukraine’s RBC Radio posted what it claimed was an audio recording of the Il-22’s crew radioing an S-O-S to controllers apparently in Anapa, on the Russian side of the Sea of Azov’s southern coast. “Urgently requesting ambulance and fire crew,” the crew radioed.
