I don't know if the two-day trip schedule was a one-off, compared to normal operations which I suppose will be hourly or day trips. A cancellation isn't a big thing then. But here we have a group that is more or less expecting to fly home in time (at least the day that was planned). It must have put extra pressure on the guys up front, to at least give it a try.
These operators/organisations/clubs need cash flow to continue flying their expensive planes.
Here in our country an organization that operates a Catalina has been forced to stop due to lack of cash flow. Because last Year it was involved in a minor incident (stuck nose gear) and the resulting time it took to get repairs done, took out the best part of the flying season, depleting the little reserves that were there.
Many of these clubs lack the deep pockets like Red Bull has to keep everything in mint condition and don't care if a show or trip gets cancelled.
