Use detacher 1 to release the shuttle. The main cockpit is on the shuttle by default but you can easily switch it. The wings on the carrier tend to fall off on initial loading so please reload the aircraft. Do not detach when craft is ascending, otherwise the shuttle will crash into the carrier. Do not fly the shuttle at max throttle as the wings tend to break up off at higher speeds. You can also easily attach a secondary craft to the underside of the carrier. I'll upload a version with both shuttle and secondary craft if there's interest. DISCLAIMER: both the shuttle and the carrier are based off of other users work. However, I cannot find the original crafts in question so please attribute the original creators if you happen to know them.
