Did the plane hit the ground before it hit the jogger?

"There was no noise". It "was 'basically gliding' as it hit and instantly killed Jones."

Those lead me to believe it was still airborne when it hit him. And that, maybe, if he had seen it, he could have ducked or thrown himself flat and avoided it that way. But this is all speculation based on incomplete information, and shouldn't be taken as any more than that. It's a tragic "one in a million", and my sympathy goes out to the family and to the pilot.
