Missed the point completely?
If they could design and fly a plane like the SR 71 back then, that long ago, WTH do they have now?
BTW, I had a neighbor that saw that craft during the Phoenix lights. He worked for Boeing as an engineer.
What did your Boeing engineer friend have to say about the Phoenix lights. We have seen the 35mm movie made by the MD and her hubby. We have listened to the Real Estate Broker who has spearheaded so much research on the topic.
Some claim we had our own UFO craft ... forgetting exactly ... by the late 50’s early 60’s.
