Re: Boeing 777-300ER Multiple Navigation Instrument Failure

Cycling circuit breakers in flight is not a good idea or condoned. And I believe actually forbidden. I clearly remember a Mayday episode where doing that led to something very catastrophic. One example of this was the LOT 767 that belly landed. While the circuit breaker hadn't "popped" fr...

Re: Delta uncontained engine failure - ATL-MCO

Even before knowing the details of the failure, a few things need to be said . . 1) Engine shutdowns are rare. I think it was noted after US 1549, that the dual failure was the first time either of the crew had ever had an in-flight engine failure. Think on how long both of those careers were at th...
