There are two photos in the ship design section of the introduction of Brown's "Rebuilding the Royal Navy": Is it possible to identify which projects they relate to? The plan on the screen is described as a frigate, and it appears as something between a frigate armed Type 42 and Type 22...

This is one of the steps on the road to the Hubble Space Telescope. At this point in the process the telescope contains a lot of Apollo legacy hardware and was designed so that the shuttle could be docked with it to allow maintenance and instrument swap-outs to take place in a shirtsleeve...

G'day all Just wondering if anyone could direct me or afford me some information on India's interest in the Douglas A-4 Skyhawk? I wasn't even aware that India had shown interest in the Skyhawk - was it for the Indian Navy or Air Force employment? Regards Pioneer
