The only VC awared in the BoB was to a Hurri pilot who was bailing out of his burning fighter when a German fighter passed in front of him. He climbed back into the cockpit and, ignoring the fact that he was being badly burned, chased the German fighter down and dispatched it before bailing out.
Many a bomber was held level by its pilot(s) giving the crew time to get out.
Aircraft most certainly did not go into death spirals just because they were on fire. The aircrew just usually had other priorities than continuing to fight. That Hurri pilot was an exception.
