Leon,
Unless I've missed something, I doubt the QE2 can do trips over the Serengeti?
As previously stated there are bigger white elephants out there...this just looks like one at the moment.
How much did MOD recently pay for a few gossamer camera carriers?
And, if you were involved, you'd take a little care with your new baby too and you wouldn't throw it out in manky weather on its first trip. I'm sure you'd want to know how well it taxy's and handles at low speeds before heading for the big stuff too.
