... , but we really need to estimate their future probability of occurrence, the future risk. These echoes of common accident phenomena, the outcomes and their recurrences, raise major questions about our institutions ... for years. In the Columbia inquiry, it was stated that there were "echoes" of the previous Challenger disaster present. Echoes that the key contributors were the same, the safety practices, internal management ...

... launching canister shortly after injection into orbit. According to The New Scientist, the shape of ECHO II after launching was flabby and elongated rather than the perfect sphere wanted for some of its communication experiments. Analysis of Malvern's radar tracks on ECHO II revealed writhing echoes that, according to their theory, arose when the very short radar pulses entered ...
