This one is a simple one that I had fun with.  I got to use hinge pieces (always a challenge but oh so much fun!)  I coated the inside with Smoothies, and the crate can fit right in there.  This was born from some of the other sets I had that used enclosures to hold crates.  I finally got ships big enough to hold some of the small personal ground craft inside!  I don't know.  You think maybe 1 main booster rocket, 2 auxiliary & 2 airplane turbines are a bit overkill?  Hey, when a critical crate has to get somewhere, don't mess around with wimpy little rockets no sir!
