So, it seems that some Blue Streaks, at least the first stages thereof, made it to Australia and to Kouru without a Belfast.
Blue Streaks made their way to Woomera by sea. They were taken by road from Stevenage down the Great North Road and thence to the London docks where they were loaded as deck cargo.
As a small boy I watched a couple start their jouney this way. Getting the load through Knebworth was a squeeze - no A1M in those days!
