Racks on which small bombs can be hung, or food, water and ammunition can be carried to isolated troops, are mounted on stub wings projecting from the under-carriage of one of the new British military planes. The high-wing monoplane was especially designed for army cooperation work. One of its regular assignments is to spot enemy artillery. The Lysander plane is powered by a Mercury radial engine and has a top speed of 230 miles an Rour, with a range of 600 miles.
