The aircraft was struck on top therefore the bullet was on it's way down, or it was fired from above, or it wasn't a bullet. There's about a 2cm long gash in the seal above the windscreen (about the size a 7.62 would make on its side).
I guess they'll recover whatever object made the hole (if it was an object) when they replace the windscreen.
Just down the road the Red Cross 1900 (Red 908) has an engine with two composite ex-propeller blades and an oil leak. As I recall this a/c belongs to Executive Turbine. Any takers on the cause of this one?
