British researchers, puzzled by the failures decided to take things in new directions: Peter Rogerson would write, "There should be a major co-operative effort at a systematic search for pre-1947 'waves,' involving, if possible, full scrutiny of national and local newspapers, and scientific and popular magazines, starting with flap periods, then other periods." Attention should be paid to "the social, religious, political and scientific background." Roger Sandell's work on a 1905 outbreak of ufo sighting in Wales had already suggested that these earlier flaps had odd facets, some of the high strangeness material echoed modern cases, but not in the ways might hope if one thought them extraterrestrial. Mary Jones encountered a sinister black clad man she identified as Satan, but would probably thought an MIB had it not been 1905 Wales. Other Men in Black were seen and one figure turned into a black dog before one witness's eyes. Noting such things only add to the complexity of the ufo phenomenon he urged progress could only be made by detailed research conducted with no preconceptions.
