Having done a Staff Ride to the dams some years ago I too was very impressed with the run-in to the Eder. Looking down from the castle (the IP) to the headland which marked the turning point to aim at the dam it all seemed very tight.
Back home I decided to have a ‘go’ in the sim, flying a 4 engined ac (C130) but with the benefit of auto throttle (to simulate the ENG) & radalt (the Nav). Even doing it by day I wasn’t able to get lined up properly and stable at 50ft, everything happened just too quickly.
