According to several Polish Mil-Bloggers something very murky happened last winter. It is still not confirmed but we have some indicators worth talking about. On the 16th December 2022 Russians launched one of her many infamous larger missile attacks. Like many before and after, it was a mess, where - aside from damage and death in Ukraine - some Russian missiles were shot down or even hit Russia itself. I reported about that back then.

That missile type is old, has a low accuracy and was only designed to be a carrier for nuclear warheads (you read this correctly). Russians removed the nuclear warhead and put a mockup on it. The idea was to fire this missile into Ukrainian airspace so that it draws the attention of Ukrainian air defense, something what Russia did already several times. That Ch-55/Ch-555 was fired from a Russian strategic bomber near Smolensk. The target was Kyiv. But instead heading for Kyiv the missile changed course and flew over whole of Belarus and into Polish airspace where it crashed near Bydgoszcz, 400km from the border. The missile wasn't retrieved and some even claimed that it never happened, but few days ago debris in a forest near Bydgoszcz appeared (Retweet) which some experts claims that it can be from a Ch-55/Ch-555). If that story is true, it would leave many questions. Was the launch intentional? Well, I doubt. But why didn't the Polish air defense react? There might be many explanations, but all what be speculative. But let that sink in that a missile which is only designed to be a nuclear warhead entered NATO airspace. Like I said, treat this information as unconfirmed, yet. But we also know that Poland and NATO significantly increased the air defense ever since.
