I'm not sure if there is a specific 'vlad x danny airplane striping fanfic' available. You could try searching on popular fanfic websites like Archive of Our Own or Fanfiction.net.
The timing of Portland Comic Con changes. Sometimes it's in the summer, sometimes in the fall. To know for sure, you should follow the organizers' announcements on their official channels.

It's hard to say exactly what it would be about without reading it. But it could involve Vlad and Danny in a situation related to an airplane, perhaps they are working on striping the airplane (painting the stripes) together and some sort of relationship dynamic or adventure unfolds during that process.
I'm not sure specifically what the 'Portland Horror Story' is about as it could refer to various things. It might be a local legend in Portland involving spooky events, like haunted houses or strange occurrences in the city's history.
There's a portland scary story that involves a forest near the city. A hiker once went in and got lost. As night fell, he started to hear growls that seemed to come from all directions. He noticed pairs of glowing eyes in the bushes. When he finally found his way out, he was pale as a ghost and said he'd never go back. He swore there was something unnatural lurking in those woods.
There are also stories where contractors work on large commercial projects. They might face challenges in coordinating with different teams, like the electrical and plumbing teams. A contractor once told me how he had to reschedule the work of all the sub - teams when there was a delay in the delivery of building materials.
