There are a few companies who do seated crew figures, in most of the popular scales. I beleive Aeroclub and Dartmoor might still have some listed, but a quick look under the figures section of, say, Hannant's webg-site should give you some ideas. Unfortunately, as seated figures are a somewhat limited market, compared to stanidng/posed figures, these tend to be relatively expenisve for what they actually are, although some nmanufacturers aren't too bad at pricing.
