Saw this on AvHerald a few days ago. We've seen this before with the 757, and wake turbulence has been a contributing factor in other large accidents, such as the AAL A300 in Queens in 2001 (I forget the number) that was caught in the wake of a JAL 747. This should be really concerning to any pilot of a medium or large category aircraft, I'm curious to see if additional requirements are put in place with regards to the A380. Definitely a good example of why wake turbulence separation is so important, in more than the local (final approach and departure) environment!
