A case of friendly bombing, but unintended:
On 29 January 1945 the American landing craft repair ship ARL-2 Amycus was anchored in Lingayen Gulf when at 1022 hrs an explosion occured about 60 feet off her port quarter. The ship was slightly damaged but shrapnel killed three sailors (S1C James Brocco, F1C James Haugh and S1C Willard Jamison) and wounded nine. Investigations revealed that it was a bomb jettisoned by a Navy SBD formation flying over the ship.
