We can’t even make radio waves that travel that far. Our best radio telescopes focused on something near that we suspect might have life don’t have enough power for us to think they can be received by an arbitrarily advanced civilization on the other end (assuming there is that happens to be listening when the signals arrive). And that is stars in our own subarm of the milky way.

However there are not a lot of airplanes (or pilots) and so it doesn’t take too many crashes before people start noticing they can’t get airplanes to someplace at all, or if they can they have to book early because they are all full (and soon after they notice seats they have booked get canceled - they won’t know it is because the plane crashed, but they know they can’t get there)
