The dashed line means the path is a guess. When the plane stopped sending GPS signals, Flightradar draws a straight dashed line to the direction the plane was heading to when losing the contact, and continues the path on the same speed until the real location of the plane is known again.
And then the dashed line moves to go to where the plane has actually gone in that time.
So, the plane hasn’t been there, this is just how Flightradar reacts to the Russia’s GPS jamming.
Many European countries have patriot missiles. They probably not allowed to be exported anywhere without a permission from USA, and if you ignore such an export restriction, you’ll end up in trouble when trying to procure arms the next time. Or, might end up. After what Trump’s done, it could very well be that this would be considered a force majeure situation. We are defending ourselves from the Russia, and of course we must be allowed to use our AD missiles for that.
So, we should probably just send to Ukraine all patriot missiles we have got and immediatelly order a lot of NASAMS and IRIS and SAMP platforms and missiles to replace them.
