Given who was flying the Spitfire, I wouldn't have ducked.
It's more auspicious to risk being hit by a Spitfire?
A pilot can care about the safety of others, and obviously demonstrate that in the way they fly...
A pilot can not care, and be oblivious of other's safety...
Or the pilot can be overtly reckless, and point a plane at another person. If driving, it would be "dangerous driving", a criminal offense in Canada.
Whenever I hear a pilot say "watch this" it causes me concern.
