I was in the Navy bootcamp in San Diego at the time.
Do you remember it??
My company was returning to MCRD San Diego on the afternoon of 11 October 1981 from our week of IT at Camp Pendleton. When our bus pulled onto the parade deck one of the recruits asked one of the DIs who had died since the flag was at half mast. The DI said “How the f*** should I know. Somebody important.” None of us found out that Sadat had been assassinated until we read the paper on the following Sunday, the 18th.
