Alerted by the sudden roar of its engines I rushed to the back door in time to glimpse what looked like a small passenger jet shooting over Worcester Park in a northerly direction.
Blog reader Victor was similarly spooked:
"A pinpoint of very bright light appeared in the sky which grew in size and flew north-east right over Central road at tremendous speed and with a deafening unusual roar.
I was with my partner and we both saw this so we couldn't both of imagined it. It was the most unusual thing we've ever seen!"
Very strange indeed.
