I hesitate to join in this never-ending debate, but I think it is worth pointing out a negative aspect of the so-called "Vulcan effect" at air shows. This is encouraging organisers to allocate such a large percentage of their budget to getting the Vulcan, that other acts are struggling to get bookings. In particular, there has been a recent comment to this effect from the operators of the glorious Sea Vixen, which is not appearing at its "home show" at Bournemouth this year for that very reason.
