Antonio Urzi never intended to show his footage publicly. It was only after he’d gathered the material for several months in a row that he began to recognize its worth. He said also that despite their size, the craft always caught him by surprise, as they were so silent.
Urzi’s videos received a standing ovation at a 2007 screening in the US.
If these encounters by his window have since continued, I would hope that he or somebody else saw to it that he be provided with an HD camera and high quality lenses, in addition to a tripod.
