“For now, we’ll wait for confirmation on the drone sighting reports in Madrid. Past incidents have turned out to be bats, balloons and plastic bags – which you can read more about here: 5 Times It Wasn’t A Drone After All.”
I understand you have to err on the side of safety but seriously...two unidentified pilots saw and confirmed them? What type UAS are they? What altitude were they at? Was it below 400 feet? Where were the pilots? What speed were the pilots flying at? Makes for a good public panic story but no real evidence.
