Jono's incendiary luggage

The maker had gone bust. http://www.latimes.com/business/la-fi-travel-briefcase-bluesmart-20180505-story.html

I think I remember the concern/risk about it being unusable due to airline battery rules being discussed. (Episode 1x60 from a quick Google)

Sounds like the lack of ability to remove the battery is the biggest issue

I planned to mention this during the previous show, but neglected to actually do so…which was a missed opportunity.
