Witness Account

Very high altitude, two rows of very distinct lights guessing 30-40k feet moving west to east.. moving about the speed of an airliner 500+ knots. Each row contained at least 20 in each row. I have pictures, my 5 year old grandson and I was watching a helicopter and comparing its location to Flightradar24… he was the one who said.. “What’s that”? I looked a little East and saw them.. two straight side by side formations of at 20 in each line (formation) Crazy to see!!
