What happened to Russia's Air Force? U.S. officials, experts stumped

Analysts expected the Russian military to try to immediately destroy Ukraine's air force and air defenses. That would have been "the logical and widely anticipated next step, as seen in almost every military conflict since 1938," wrote the RUSI think-tank in London, in an article called "The Mysterious Case of the Missing Russian Air Force." Instead, Ukrainian air force fighter jets are still carrying out low-level, defensive counter-air and ground-attack sorties. Russia is still flying through contested airspace.
