Back in April Dennis Drabelle, Washington Post contributing editor, wrote about Titanic books but got the date it sank wrong. He wrote it sank on 15 April. Oops! That prompted a letter, actually a very large one, from a fifth grade class at Burning Tree Elementary School in Bethesda, Maryland.

Dear Mr. Drabelle,
    We are fifth grade students at Burning Tree ES in Besthesda, Maryland and we have been studying the Titanic’s tragic sinking and the lives of some of the survivors. In your April 15, 2012 edition of The Washington Post, you stated that the Titanic hit the iceberg on April 15, 1912. Based on our research, the Titanic hit the iceberg shortly before midnight on April 14, 1912.
Sincerely,
    Mrs. Reed’s fifth grade class

That about says it all. Here endeth the lesson.
