During the Cold War days, a Russian pilot is captured by the US Army and locked up for interrogation.
US interrogator: "Tell us about the plans of the MiG-50 Fighter!"
Russian pilot: "I don't know" He is beaten up, then he's interrogated again...
US interrogator: "Tell us about the plans of the MiG-50 fighter!"
Russian pilot: "I have no idea about anything, I swear!"
He is beaten up again, then again and again, and finally the Americans get tired of interrogating him, so they let him go back to Russia.
In Russia, when he first meets his pilot comrades, he tells them:
"Comrades, learn the MiG-50 plans well, 'cause the Americans almost had me killed for not knowing them!"
