I was outside on a ladder on the front porch taking down christmas lights, warm weather for this time of year clear, partly cloudy, blue skies.It was approx. 1 pm. heard bizarre popping sound. turned around to look up and noticed perfectly, shaped donut-hole contrails heading to the sw at high altitude and extremely high rate of speed. i am a 30 yr retired boeing employee from the space division at huntington beach, ca.I retired with a secret clearance. i worked in manufacturing and inventory management. i have seen, watched, and heard many aircraft and rockets over my career, whether at vanderberg or edwards af bases or long beach airport when it existed. i knew immediately that this was unusual. i immediately got down, ran into the house to grab my camera and take some pics of the contrail rings. by the time i got back outside, the contrails were gone over my house and towards the sw. my guess is extreme wind at high altitude. this object flew directly over my house and was gone within seconds.
