Genuinely curious about this one. I'm over in Glasgow so obviously wasnt there myself, but I've been following triangle craft reports from the US for years and the I-70 corridor keeps coming up again and again.
Few questions for anyone who saw it - how long was it hovering before it moved off? And did it make any sound at all? The silent ones are the ones that really get me, because conventional aircraft that size just don't work that way.
Also was the lighting pattern the classic three white corners with a red centre, or something different? That detail tends to separate the TR-3B crowd from the folks who think it's something else entirely. Would love to hear from anyone who got a decent look at it.
