... Less than 1% of 20cm observing time would be lost to bad weather. ... Over the winters of 2002-2004, the so-called "swap" scheme has been used to give 3mm observers some robustness to poor weather. With this scheme, a pair of 3mm and centimetre proposals are partnered and scheduled typically a few days apart. At the discretion of the 3mm observer, the order of the 3mm and centimetre proposal can be swapped to give the 3mm observer the best chance at good weather. ...

... Concept Spacecraft . ... The proposed lentiular design concept for the Apollo spacecraft was one of several unorthodox designs rejected in favour of the more familiar conical shape which was lighter and less complex.The lenticular design was a ?road not taken?, losing out to less challenging configurations.It is strange to think that if history had proceeded differently, each Apollo crew could have ended their lunar mission by gliding to a touchdown on a runway at Edwards AFB in a flying saucer! ...
