Lets not forget that the weather actually accounted for a number of no-shows this season as well.
A day at Duxford, Southport, and Leuchars were cancelled due to the weather en route or at the event, Fairford and Cosby being completely washed out altogether.
Besides, the main problem with the Vulcan isn't so much it going u/s, its the time it takes to get the parts and MA techs available to fix the problem. That unfortunately can take weeks.
I truly hope its able to fly next season, it would be a massive shame to have come this far only to be grounded after a handful of shows.
