The "C" is a one-seater. I can't find any reference to the "chute sighted" claim, but hope that's true. Still, this many hours without some sighting or contact is worrisome.
Edit: Just found a news story that says "witnesses reported a chute" but that's all.
I know the C is single seat just couldn't get the link to work on our slow server so didn't read the article.Sure hope his egress was uneventful.
