JERUSALEM (Reuters) - Abie Nathan, an Israeli peace activist who blazed trails to Egypt and the Palestinians that his country would eventually follow, died on Wednesday. He was 81. Nathan famously piloted a private plane, dubbed Shalom (Peace) 1, to then enemy Egypt in 1966 and was twice imprisoned by Israel for meeting Palestine Liberation Organization chief Yasser Arafat in the late 1980s and early 1990s when such contacts were illegal.
