Wanted to give an update on the hotfire anomaly investigation. Progress continues. The anomaly originated at the main oxygen valve on one of the BE-4 engines, which was later confirmed by hardware recovery and inspections. Extensive component-level and engine hotfire tests have been conducted to understand the failure mode better and inform mitigations. The path forward is clear. We're making small modifications to the valve that can be quickly retrofitted to existing engines. We’re manufacturing the updated hardware, which will be ready by the end of this month. In parallel, we're working through the remaining fault tree analysis.
