Notes on verification

Confirmed by Wikipedia's own crash article and a cross-referenced March 1945 timeline page, but these largely stem from the same Wikipedia family of sources; a third Wikipedia article corroborates general circumstances without naming Kępa specifically. No fully independent primary source verified.
