I know this doesn't answer the original question, but the thread seems to have morphed into the largest "witnessed" cratering event.
Kaali is not?officially witnessed, but it certainly could have been.

The Kaali group of craters, on the Estonian island of Saaremaa,?are estimated to be only 4000 (+/- 1000) years old.
The largest is?about 110 meters in diameter and about 22 meters deep.???Some iron fragments (Kaalijarv, IAB main group) were found associated with the craters.

Cheers,

Frank

Wabar may well be a witnessed fall.? It also produced a 13-m crater.
