In order to get the best possible access to necessarily restricted aspects of crew training, McNally says he was fortunate in that National Geographic and NASA worked out an arrangement that provided him an opportunity to photograph rarely seen parts of the training process.

"The Geographic reserves certain material for publication, but the bulk of the material that I'm generating becomes public domain and part and parcel of the NASA archive," he says. "It has worked out for me in the sense that I temporarily became a NASA photographer."
