Similar sentiments here, although I can't agree with the 'sour taste' of the final flight, it was always blindingly obvious that to publicise it would have caused mayhem around Doncaster airport.
My wife was passionate about 558, but even having seen a Canberra fly she just wasn't interested, and several times has said they would do better to get another Lancaster back in the air. I could see the attraction of WK163 from its historic perspective and it being a 2-seater, but support to achieve the same as for 558 was really never really going to happen.
The third video in the email newsletter is mainly an edit of the final year of flying and glorious, the final of the trial fast taxy (taxi if you wish) just emphasises what we have lost. There may well be more interest when she does public fast taxys next year, but unless they block off 'Dogger's Lane' I can't see them making much money out of it. The mound gives a far better view than any viewing point on the airfield will, and all future public events are really only likely to attract useful numbers of people from a relatively small geographical area.
And speaking of 'finals', with the fall-out from Shoreham will we even see a Vampire, Venom and Sea Vixen fly together again?
