Why the skies over Ukraine have proven so deadly for Russian pilots

I hope that streak continues.

Ukraine needs to blow all of the Russian air craft out of the sky, and then take care of the rest of the rubbish MAJ Dale E. Wilson, Ph.D.

There are a whole host of reasons why Russian pilots have experienced less than positive success in Ukraine and not the least reason is their lack of preparedness along with a tenacious Ukrainian military that has received Stinger surface to air missiles and other weaponry from around the world, which has negated much of their success against Ukraine forces... I fear that Putin, in his inimitable way, will reach his breaking point and use a tactical nuclear weapon on Ukraine, which very well may kick of WWIII! A precedent has been set where Russia is holding the world hostage so-to-speak, with their threat of using nuclear weaponry... Hmmm.... I wonder what this says to China, Iran (who is close to having nuclear capability) and other nuclear capable countries... Just saying...
