The article mentioned that this was bad, particularly if the inboard engines went missing, since they tend to take the outboard engines with them. The question is, if an engine falls off a plane during flight, is that an automatic downer for the aircraft, or are there certain admissible scenarios? If an outboard engine falls off a 747 in flight, can the aircraft recover? Shortly after reading the Business Week article, I made personal note of the 'swaying engine pods' phenomenon on a PIA flight to Lahore. It really is rather disconcerting if you don't know what is going on. Does anyone know what degree of freedom they have - is it just in a single dimension perpendicular to the fuselage longtitudinal axis, or can they move back and forth as well? Are there any clean functions that describe the movement, or is it erratic? Terry? Brad_.
