That diagram looks like a Bond villains lair. Only thing missing is a pool with sharks.
This bullshit story was so widely spread even Donald Rumsfeld went for it.
Here is how it ended.

US special forces and their Afghan allies occupied Tora Bora. They painstakingly searched Gree Khil mountain and the surrounding area. They found no underground fortress, no hydro-electric power plant, no 2000-room hotel, no ant farm, no iron doors, no ventilating shafts. The troglodyte Lair of Bin Laden turned out to be mythic.
LOL!
I thought the same thing, but definately needs the shark pool.
