the default Norden sight (yellow). Be in cockpit. Press to switch to the next cockpit/gunner position, this is the bombardiers position, the one just after the cockpit and one before the nose gunner. Here you have all the important gauges you need on the left. Now press shift F1 and there you go. You have to be level for at least 30 secs for the gyros to stabilise and then the sight appears. Alternatively, i created a Norden Bombsight cross which never disappears, more authentic than the yellow.
