Lincoln & The Flying Spying Machine

S1 E5: May 31st, 1862: President Abraham Lincoln is pressing for a swift end to the Civil War. As his army bears down on the confederate capitol, Lincoln has a radical new machine above the battle--a hydrogen filled spy balloon, equipped with a telegraph that can instantly report on enemy troop movements. As the Union army comes under intense rebel fire, commanders on the ground use the information from the reconnaissance balloon to turn the tide against the Confederates.
