In April 1916, Wallis met Earl Winfield Spencer Jr., a U.S. Navy aviator, at Pensacola, Florida, while visiting her cousin Corinne Mustin. It was at this time that Wallis witnessed two airplane crashes about two weeks apart, resulting in a lifelong fear of flying. The couple married on 8 November 1916 at Christ Episcopal Church in Baltimore, which had been Wallis's parish. Win, as her husband was known, was a heavy drinker. He drank even before flying and once crashed into the sea, but escaped almost unharmed. After the United States entered the First World War in 1917, Spencer was posted to San Diego as the first commanding officer of a training base in Coronado, known as Naval Air Station North Island; they remained there until 1921.
