• A rough sketch map. Florida is at the top left, the Bahamas to its east, Cuba, Hispaniola and Puerto Rico along the bottom as the Greater Antilles, and Bermuda at the top right. A dashed red triangle joins Florida, Bermuda and Puerto Rico with a question mark inside. A blue arrow, the Gulf Stream, runs up past Florida and curves northeast. A note says the Sargasso Sea surrounds Bermuda, and that there is no official boundary.

• A plan of Flight 19’s planned route. From Fort Lauderdale on the Florida coast a line runs 56 miles east to Hens and Chickens Shoals for practice bombing, 67 miles further east, then 73 miles north-northwest across Grand Bahama, then 120 miles southwest back to Fort Lauderdale. In the bottom left, the Florida Keys are labelled where Taylor thought he was. A dashed red arrow at the top right says where the flight was really heading: north of the Bahamas, east of Florida.

• A rough sketch map of South America and the Caribbean. A line runs from Rio de Janeiro, which Cyclops left on 16 February 1918, north to Barbados, where she called on 3 and 4 March 1918. From Barbados a dashed red line heads north to a question mark labelled never heard from again.

• A bar chart of Gulf Stream speeds: fastest near the surface, about 9 kilometres per hour; average, 6.4 kilometres per hour; wider and further north, about 1.6 kilometres per hour.

• Two compass dials. On the left, labelled most places, the red magnetic needle points a little away from true north. On the right, labelled on the agonic line, the red needle lines up with true north and no correction is needed.
