I don't think it's that serious an oversight, as I am sure many on here had to take a very careful look before realizing it wasn't a 737NG. I know I did. That's really immaterial, especially since one "Bus" looks pretty much like another these days.
More importantly, I'd like to know if anyone reading this has had a call from them and if they've only restricted themselves to contacting NG-typed candidates.
Thanks
