We received one break in timing; no passenger ship was on Luna and none was due until 7 July. We could have coped—suckered a ship’s officers to "dine with Warden" or something, then mounted guard on its senders or dismantled them. Could not have lifted without our help; in those days one drain on ice was providing water for reaction mass. Was not much drain compared with grain shipments; one manned ship a month was heavy traffic then, while grain lifted every day. What it did mean was that an incoming ship was not an insuperable hazard. Nevertheless was lucky break; we were trying so hard to make everything look normal until we could defend ourselves.
