  1. Where is the follow up to this report?
    What was the AIB's conclusion? I can tell you as fact that the aircraft was NOT engulfed in flames as the article above states. The injuries were very minor and the pilots handled the situation very professionally.

    With the inability of the AIB to call out its own in other incidents (some of which the causes are obvious to anyone familiar with aeronautics), I can understand Delta's move to only alert the NTSB.

    I would bet that the end result, the engineers were immediately allowed to replace the engine and the aircraft departed.
