Thanks chaps (if indeed you identify as such), there was something strangely comforting about seeing FlyBe Dash-8s snoring overhead inbound Southampton or Exeter. Mate had to do Southampton/Hamsterdam fairly regularly and I planned to get a snap of him on digital zoom one day - stymied by the collapse. Perhaps those services will reappear in time.
Think the Zep ended up back at Calais, the flight seemed to have originated from there. Getting pretty dark by the time it was heading over the Channel (and last time I looked) but I guess night operations are OK - indeed I remember seeing Europa floating around at night in the 1980s with the advertising lights ablaze with some message or other after aerial advertising legislation was relaxed.
