It shows the unbelievable precision required to build a new tunnel given the amount of existing tube lines and other, often unexpected, underground structures. Well worth watching.
I guess they don't put everything on BBC Worldwide due to costs (getting permission from rights holders etc.) and instead prioritise those things they think are likely to sell.
It's as if they _want_ us to BitTorrent Great British Bake-Off.
Things are probably going to get trickier in this regard shortly though once user accounts are made mandatory. Despite the BBC's claims, I wouldn't be surprised if this is step one in a plan to ensure all viewers have paid the UK TV Licence fee, especially following the recent closing of the loophole that allowed you to legally view iPlayer content in the UK without a TV licence if you didn't have a physical TV set.
(For those not familiar, UK residents are typically required to pay 147 quid or so a year if they own a TV or access the iPlayer service, which contributes to funding the BBC. Hilariously there is still a discount if you only have a black and white TV...).

I should mention that trespass on live railways (and a few other places) is a criminal offence throughout the UK, so you must get permission if you want to go anywhere on them not open to the public. Subbrit occasionally arrange tours of closed tube stations such as Down Street and South Kentish Town.
Are we talking CFM or specific impulse?
