GE90 Makes The Old JT9D Look Like A Toy!

 This video isn't new, but it's from the History Channel and very well done.  It's simply stunning to see how large and powerful the GE90 engine really is - with a world record setting thrust of 127,900 pounds during testing!  The max "rated" thrust is 115,000 pounds.

 It's also cool to see some great images of the intensive testing that they put these engines thru.  It would be interesting to know if this engine would have survived the massive bird ingestion that Cactus 1549 had.  After seeing this vid, I think it might have kept right on running.

 When the 747 first arrived on the scene in 1970 with the Pratt & Whitney JT9 engines (43,500 pounds of thrust), everyone was in awe at how big these new engines were.  And now, the view in this vid of the GE 747 testbed aircraft with one GE90 and three engines similar in size to the old JT9 is almost comical to see.  What a difference!

 The GE90 has been in service on 777's now since 1995, but  despite its amazing performance, you don't really hear a lot about it these days.  Kinda proves that it's not only huge, but reliable too.  Well done!
