Yeah…that’s pretty interesting. And odd. I mean, there have probably literally been tens of thousands (if not hundreds?) of crossing incidents like that over the past X years but this one had some odd alignment of circumstances to make it so. Even in our light jet, we don’t really make any unusual deviations due to crossing wake turbulence when level in RVSM. I’ve crossed behind FedEx MD-11s, 747s, A330/340s, and never felt anything. I have hit wake in the terminal area…a brutal hit as we crossed it at 90 degrees, just a big slam. And I have hit it behind a Marine HMX-1 helo in a Cessna. That was exciting.

It’s indeed a series of circumstances colliding, still very interesting. I remember a Alaska Airlines 737 on approach in Juneau INTL a few years ago having a uncommanded right roll to a bank angle of somewhere between 60 and 90 degrees due to turbulent air. Creepy stuff when you come to think about it, disturbances we can barely observe.
