Rory Bushfield and Janice Phelan, husband and mother of the late Sarah Burke respectively, just had their flight cancelled to get them to Sochi in time for Women's halfpipe. They should be there to represent her. Sarah's one of the main reasons freeskiing is in the olympics, and she's surely the reason there's a women's discipline there.

Hopefully someone at Air Canada or Westjet or something is able to help them out.
