HD, thanks for the response and totally agree with you. It seemed to come from Richmond and caught my eye because of the sun - it was making odd maneouvres and it was difficult to make out at first as it seemed to "hang" there for ages then it appeared right above the Green and I could clearly see small "lights" or spark like objects "falling" from the aircraft. 3 of us saw it so this is not just me. Extremely curious to find out what it was.
Cheers
