Either way, I'd see hs2 as a big gamble
I'd see it as dead in the water . I'm being realistic in saying that very few people are going to use HS2 to travel to London or V.V. to catch a flight. They are going to use road transport (coach or car) . Use the money to improve these (runway extension/better road links) We already have rail links, instead of getting there faster just get an earlier train .
