So how goes the 'feasibility study' into Boris Island? Have the surveyors been hired and the architects consulted?
"The current work draws upon in-house expertise and poses no extra cost to the GLA. I am expecting a progress report shortly. If this recommends that further work is undertaken by outside specialists then this option will be fully costed."
In-house eh? I wonder what that involves. A quick visit to Simon Milton's office perhaps, or an even quicker phone call to David Cameron?
How about Assembly Member Jenny Jones? She seems happy to help:
"Will the study being undertaken by GLA officers in to your proposal for an airport in the Thames Gateway consider the difficulties to construction that could be posed by the wreckage of liberty ship SS Richard Montgomery, which sank off the coast of Sheerness in 1944 carrying a cargo of explosives, around 1,500 tons of which are reportedly still on board the wreckage."
Ah yes, that old wreck. Surely Boris considered that before announcing his scheme? Didn't he?
"Thank you for highlighting this important issue. I will make sure that my officers consider the implications of this in their current evaluation of Thames Estuary airport options."
Phew, well done Jenny. That could have all got very messy there indeed.
