The previous book they worked on was DRIVE which features ground vehicles. With BLAST, they take to the skies and design aircrafts and flying ships.
The 128-page book is filled with concept sketches and paintings. There are lots of aircrafts coming in all sorts of interesting shapes and designs. There are bulky ones, those that look like they have sails, vertically skewed ones, others, and one that I found the front to look like Iron Man. However, there are no gigantic deep space exploration crafts like those from Star Trek.
