saw 3 bright white orbs flying in a straight formation that looked like the center of Orions Belt

Wife, daughter, and I stargazing from our campsite. I work in sales at a large multinational investment bank and wife is Oxford post-grad Product Manager at a public utility. I saw what at first believed to be Orions Belt, distinguished by it's bright 3 star center, until I had a vertigo effect and realized the 3 solid bright white (not yellow) orbs, which looked like stars, were moving. I couldn't believe what I was seeing, I asked my wife "are you seeing this?". My wife and 5 year yo daughter seeing it too. If they had not moved, they would otherwise look like 3 bright stars in the sky, such as part of the Orion Belt constellation. They moved quickly, in a straight line, each orb equally distanced from the others, faster than the speed of the international space station flying overhead. No noise. No trail. We lost our vantage point in the trees, so we moved, and expected to see the 3 lights in the next clearing but they did not return. This was the most bizarre thing we have ever seen, and likely ever will.
