+is a flight simulator which uses Vulkan API, developed by [@pmathia0].
+As an aerospace engineering student, Peter has always been interested how
+a flight simulator works under the hood.
+The development of SeniorSKY started as a hobby project during university
+studies.
+
+SeniorSKY uses real-world elevation data with 1 arc
+second precision and can render the whole globe in real dimensions.
+During the flight, the terrain tiles are loaded dynamically based
+on real GPS coordinates of airplane, with a decreasing level of detail
+further from the camera. This is achieved using a combination
+of a terrain-quad-tree and GPU tessellation.
+
+Notable changes since last month:
+
+- atmoshperic scattering
+- improved fog
+- FXAA + HDR tonemapping
+- terrain data preprocessing using compute shaders
+- performance optimizations
+
+Short-term plans:
+
+- replace imgui-rs by egui
+- implement sun position based on datetime
+- add terrain bump-maps to visualize gravel
