Along with the large collection of trains, the Technik Museum in Berlin is also home to many aeroplanes.
Starting with examples of early attempts at machines that could fly
it charts the development of aeroplanes through the 20th century.
As well as many full aircraft on display, many engines are on show with explanations as to why they were developed and why some are now no longer in use.
On the terrace, you can get a close-up view of the flagship (flagplane?) of the museum.
Back inside, some of the ground-based tools to improve flight from horizontal wind tunnels to flight simulators can also be seen.
Once again, the skills of model builders, who put together this replica of a previous Berlin aircraft collection, are also on show.
