Gold - interesting choice for a flying surface such as a wing, possibly not the most effective choice of material. Mind you, wasn't the Lunar Excursion Module swathed in gold foil? So perhaps folk with such "wings" are well suited to operate in places with no atmosphere. Like the average multi-squadron wardroom on board, for example...
btw - JNo, your muppet picture isn't visible through our ME connection. Does it perchance contain traces of pork products?
