The SAI KZ IV was a light twin-engined aircraft first built in Denmark in 1944 for use as an air ambulance. A single machine was built during the war, and was used by Folke Bernadotte while negotiating for the release of Danish prisoners in German concentration camps. It is now held by the Danmarks Flymuseum and has been restored to its original wartime configuration and markings. A second aircraft was built and flown in 1949, remaining actively operational until the mid 1960s.Photograph: Slaunger

A male and female mandarin duck (Aix galericulata) at Martin Mere, Lancashire, United Kingdom, showing the sexual dimorphism of the species. The adult male has a red bill, large white crescent above the eye and reddish face and "whiskers", as well as a purple breast with two vertical white bars, and ruddy flanks. The female is similar to female wood duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a small white flank stripe, and a pale tip to its bill.
This species was once widespread in East Asia, but large-scale exports and the destruction of its forest habitat have reduced populations. A large feral population has been established in Great Britain.Photograph: Francis C. Franklin
The equirectangular projection is a simple map projection attributed to Marinus of Tyre, who Ptolemy claims invented the projection about AD 100. The projection maps meridians to vertical straight lines of constant spacing, and circles of latitude to horizontal straight lines of constant spacing. The projection is neither equal area nor conformal. Because of the distortions introduced by this projection, it has few applications beyond base imagery to be reprojected to some more useful projection.Map: Strebe, using Geocart

Quaker guns in former Confederate fortifications at Manassas Junction, Virginia, in March 1862. Quaker guns were widely used as a deception tactic in warfare during the 18th and 19th centuries. Although resembling an actual cannon, the Quaker gun was simply a wooden log, usually painted black. The name derives from the Religious Society of Friends, or Quakers, who have traditionally held a religious opposition to war and violence in the Peace Testimony.Photograph: George N.

Kampoeng Rawa is a tourist attraction in Ambarawa, Central Java, located within the green belt around Lake Rawa Pening. Opened in August 2012, it is owned and operated by twelve groups of farmers and fishermen who were funded by the Artha Prima Credit Union. It is intended to improve the welfare of local farmers and fishermen while promoting an understanding of the lake's ecology. Facilities include a floating restaurant, pendopo, crafts centre, fishing area, and docks. It has been challenged for its lack of permission to build in the green belt and the possible ecological impact.Photograph: Chris Woodrich
