I trust Boom has smart people working on these things, but... model aviation doesn't scale up[1].

It's interesting they're going with a scaled-down model instead of a full-scale testbed. The article seems to incidate they're wanting to go from the scaled-down model as a PoC, then onto an actual airline that JAL want's to fly. I'd think they'd need a full-sized PoC first...

That's chump change for an airline. Doesn't really signal strong support or anything - more of a curiosity I think. A Boeing 737-800 costs around $100 million, for comparison.
