View attachment 500411 A TWO-STOREY AIRBUS: The large Junkers G.38 airliner has been modified to meet the demand for extra passenger space by the addition of a "second storey" on top of the fuselage, between the wings. A smoking compartment has also been provided. The machine will be put into service between Berlin and London. G.38 Stock Photos and Pictures | Getty Images
Ok...slight exaggeration. It weighs just over a pound and a half.
Sadly, during storage the underside of the starboard wing "puffed-out", probably from heat expansion as that wing has no hole to the hollow insides, and would be difficult to fix. You can't just simply sand this defect away as the whole skin of the aircraft is corrigated.
