The Vestibyul was barely large enough to accommodate a supine human. At one end was a flange that mated with the forty-centimeter ring on a Luk. Having slithered feetfirst from the Luk into the Vestibyul, a cosmonaut had just enough wiggle room to get his feet aimed down the legs of the Orlan suit that was attached to the other end, its door hanging open. Before doing this, however, he would seal off the Luk by manually putting its diaphragm into position and bolting it into place with a ratchet wrench.
I've just realized that this entire section (including the paragraphs that came before it and the ones that will come after) is an explanation for why this book is nearly 900 pages. Theres so much exposition and technical detail, it reads more like a manual than a story at some points. Bring back the plot Neal, stop playing with me. Im not here to learn about how a space man gets into his space suit (unless this info is somehow relevant to the plot, which i doubt.)
