Jubilee tunnels from Aldwych to Charing Cross?

Tell me more!

The original plan for the Jubilee Line was that after Charing Cross it would
run to Aldwych (thus making that station a bit useful - tunnels along the
Strand were built but never used) then along the course of the Fleet (hence
the planned name "Fleet Line"), taking in Holborn Viaduct (now City
Thameslink) and Fenchurch Street, then down to Surrey Docks (now Quays) and
then over the mainline rail to Hayes (which would have brought the tube into
that part of the world - I wonder how Fare's "Fair" would have gone down in
such circumstances). However the project only got to Charing Cross and the
remaining plans never materialised.
