The account
APRO moved to Tucson in 1960 and emphasised scientific field investigation, with consultants such as James E. McDonald and Berkeley engineer James Harder, its research director from 1969 to 1982. J. Allen Hynek rated APRO and NICAP the two best civilian groups of their time. APRO remained active until 1988; part of its membership formed MUFON in 1969.
The sceptical view
APRO's investigators, like other civilian groups, were criticised for favouring the extraterrestrial explanation.
