Constitution Incident

First Officer Commander Lara is involved in an incident on the USS Constitution (NCC-1700) where she overrides her captain's authority. The order results in the destruction of one of the ship's shuttlecraft as well as the loss of two crewmembers on board. A later investigation reveals the Commander acted appropriately and probably saved the Constitution. The captain did not agree and removed her as first officer. While exhonerated of wrongdoing the incident leaves a "black mark" on her record.
