The mysterious disappearance of Putin’s aviation from the war in Ukraine: “They avoid fighting”

The Ukrainian fighters whizzing undisturbed on the Russian frontline re-propose the mystery of this war: what happened to the Moscow Air Force? On paper there is no match: it has 1,435 fighter jets against 98 in Kiev, an advantage of almost 15 to one. And they can’t even be said to be old, because Putin has spent billions to buy 400 new ones and update a substantial number of the older ones.
