When I talked with a native speaker, I said
SpaceX Demo-2 was scheduled for launch to the International Space Station on 27 May 2020. NASA live streamed at launch. I off work early to specifically watch that. When I got home, I found that the launch was canceled, which made me a little bit upset. But the whole thing is interesting
... But the whole thing was interesting
I understand that's because we need to keep the tense consistent. However, my interest to the launch is still there. I will watch that launch at 30 May, which is the rescheduled time.
In this particular situation, should I use "is" or "was"?
