I was lying in bed facing a window which is 40cm wide. the sky was grey. as i lay looking out of the window i first saw 2 bright lights heading in a similar direction of the flight path of planes heading to manchester airport. as the 2 lights were passing a third light shot up behind them as if catching them up in a chidlike way. the 2 lights definitely were slowing to wait for it! they passed the window. my window has white organza as a curtain. i jumped out of bed and ran to another window for a better look. they had gone. the lights didn't follow the flight path exactly, they were slightly off course but heading in a straight line. when i looked out of the second window, there was a double rainbow. i have a photo downloaded from twitter from someone else who saw the rainbow. i first thought the lights were stars or maybe a plane as i see them so often.
