So are they building their own plane, and launching a new airline? Will they also sell the plane to other airlines? Or is this trying to be vertically integrated, like Apple / Tesla? Also, I echo the other sentiments here about the name, really don't want to fly on an airline named "Boom". Nor "Explode", "Kapow", or "Blast". And god forbid if one of their planes crashes during test flights, the PR nightmare that would result.
