Bit off topic for me as I'm usually more of a cryptid person, but this thread caught my eye. I'm in Edinburgh so obviously nowhere near Phoenix, but my brother-in-law was actually visiting Arizona last week for work and mentioned seeing something strange in the sky on Tuesday night. He's not into any of this stuff at all, proper sceptic, but he sent me a voice note about it and seemed genuinely shaken.
He described a large triangular shape moving completely silently, no blinking lights like you'd expect from a plane. Just three steady points of light in a triangle formation moving slowly then gone in seconds.
Did the craft you saw make any sound at all? And roughly what time was it? Trying to work out if it matches what he saw. He thinks it was around 9pm local time but he's not 100% sure. Would love to be able to send him this thread actually, might finally get him interested in the subject.
