Right now, watching the Horizon documentary on how they moved the blue whale skeleton into the main hall of the NHM and my face is like this 
WTAF? The money they must have burned through to move the skeleton. There's the chief guy in charge who had to fly out to California to go whale watching so he could personally witness the dynamics of the whale's movements. Same guy then had to fly to Ireland to have a ganders at the beach where the blue whale washed up.
Then there's the specially designed and custom made contraption used to move the skeleton's head about 20 foot across a room.
And currently watching several curators gingerly using cotton buds to dust a bone that looks about 12 feet in length.
I'm thinking that if this was taking place in the private sector you'd be given half a day to get the whole thing moved, dusted and set up again. And certainly no whale watching trips in the process.
