"London, do you have time for a question?"
"Go ahead..."
"We've never been to London before, this Willo2D, do we just descend at our discretion to make the level restrictions down to seven at willo?"

This was under normal ops, and maybe it's not such a stupid question, but it made me chuckle, and the BA behind.
At least he asked!
