The first air raid in history occurs; Austria launches pilotless balloons against the city of Venice

An airstrike, air strike, or air raid is an offensive operation carried out by aircraft. Air strikes are delivered from aircraft such as blimps, balloons, fighter aircraft, attack aircraft, bombers, attack helicopters, and drones. The official definition includes all sorts of targets, including enemy air targets, but in popular usage the term is usually narrowed to a tactical (small-scale) attack on a ground or naval objective as opposed to a larger, more general attack such as carpet bombing. Weapons used in an airstrike can range from direct-fire aircraft-mounted cannons and machine guns, rockets and air-to-surface missiles, to various types of aerial bombs, glide bombs, cruise missiles, ballistic missiles, and even directed-energy weapons such as laser weapons.

Venice is a city in northeastern Italy and the capital of the Veneto region. It is built on a group of 118 islands that are separated by expanses of open water and by canals; portions of the city are linked by 438 bridges.

July 15 is the 196th day of the year in the Gregorian calendar; 169 days remain until the end of the year.
