what earthly purpose would a differential serve in an aero engine? I have never heard of such a thing. The only gearing in a typical engine is the propeller reduction gearbox, which can look similar to a differential, but doesn't do the same thing. It's just a reduction gear. There can also be gear drive in the camshaft system and the supercharger, but none of those are differentials accommodating different output speeds for a single input speed.

- It presumably means the prop gearing. The horseshoe oil tank of the 109G's Daimler-Benz DB 605 engine sat over the prop shaft, and an oil leak from that tank, perhaps due to vibration or fragments from propshaft failure, was the suspected cause of the fatal engine fire. A rival theory is that there was a leak from a glycol coolant pipe, glycol being flammable. But a lot could go wrong with the DB605, not least due to its use of plain bearings instead of ball bearings and its use of substandard alloys, these problems reflecting Germany's weakness as to supply of both finished goods and raw materials.
- Although the article is better than it used to be, it perhaps understates how futile Marseille's career was. As far as I recall, all of his claims were for single-engined fighters, meaning he simply wasn't doing his job, which was to protect the Afrika Korps from Allied air attack. He never claimed a bomber or an anti-tank aircraft and was concerned solely with inflating his own personal score against Allied fighters, a mistaken notion encouraged by Reich propaganda. The article could perhaps go into how damaging the 'cult of the ace' was for the Luftwaffe. The fact that no one else in JG 27 actually did anything much except record Marseille's supposed victories (of which about a third were overclaims), and that the whole wing had to be withdrawn from theatre due to failure in morale after Marseille's death, does kind of speak for itself.
