It took me awhile to figure out how to make a biplane. The sceret is that you need to start out with it being one block thin. Anyways, there's any open hatch on top, where you can sit in a chair (minecart) and put items in a stoarge chest. This is made out of lime and green clay, with dark oak wood details. I hope you enjoy putting this schematic in your world and have fun with t\it, but just dont claim that it's your own.
