support, and air force. the ukrainians do have an air force, they do have trained pilots, the new york times had some interesting reporting about the ukrainian air force, and how it's operating in, quote, but the times says, near total secrecy. one of the pilots they spoke to said, quote, in every fight with russian jets, there is no equality, they always have five times more planes in the air. despite being outnumbered, ukrainian paul pilots have been successful at preventing wider bombings. they've intercepted some missiles. talk to me about this, they are vastly outnumbered by russian ships, how is the outlook for the air force in ukraine? >> so, that's one thing, it's not fully known, it's kind of hard to tell from the sources. partially because i think they wanted that way. but they're making life difficult for russia. in terms of invasion, for russia, they want to have their supremacy, where they have fire aircraft, bomber aircraft, operating over ukrainian forces at all times, being able to bomb, them the reconnaissance, all this kind of things.
