Asimove responds that he cannot attend conference ("Surely you can't really plan to have a whole series of conferences, stretching out ad infinitum, each one of which will have a program booklet beginning with my apologies for not being present? I can scarcely conceive of anything more wearisome for the assembled conferees."), and enclosing his remarks. [See next item.] -- Document signed ("Isaac Asimov"). N.d. 1 page, 4to, creased at folds, with tape on 4 corners and top right of page. Asimov explains to conference attendees why he cannot attend. ("It seems ridiculous (I know, for everyone tells me so) that someone like myself who has spent his life in writing of trips across the Galaxy should, in real life, refuse to enter an airplane, but it is so. We all have our unreasoning fears and airflight is mine.")
