Mrs. Futrelle is one of a number of 1st class surviving passengers oftenly placed in different lifeboats. I believed she left along with Mrs. Harris aboard Collapsible D.
Mrs. Futrelle gave different versions of her escape. However Mrs. & Miss Lines mentioned that Mrs. Futrelle was in their boat (No. 9).
Here is one of the interviews by Mrs. Futrelle: "After I left the ship two collapsible lifeboats were launched. In the last one was Mrs. Henry B. Harris, wife of the theatrical manager; Mrs. Thorn and Mrs. Hoyt, that I remember....the ship at that time had sunk to within 15 feet of the first deck... " (The Atlanta Constitution, April 26 1912 )
