Even the Goering account can be explained, without the DVIIf being faster than the 220 hp SPAD XIII or 235 hp SPAD XIII. Goering and the SPAD pilots are low to the ground, right? The DVII, according to French pilots, claiming to encounter DVIIs frequently, is at best, according to them, as fast as the 220 hp SPAD XIII and we would guess, but not know for a fact, slower than the 235 hp SPAD XIII. The DVIIf can out climb the SPAD XIII and has Camel like maneuverability, no? Your best defense against such attributes, as a SPAD pilot, is your ability to dive away, but you are low to the ground, so you cannot dive. If you are the SPAD pilots, are you in a hurry to catch Goering, at low altitude or sea level? No way, because Goering will just climb over you and go right on your tail, using his Camel like maneuverability and 220 hp SPAD speed performance. Still, where are Allied accounts of super fast, high altitude DVIIs, running down 235 hp SPAD XIIIs, in straight and level flight, at combat altitude, exempting engine trouble or other malfunction of the 220 hp or 235 hp SPAD XIII?
