Oh, in that case we've observed one of our (indoor) cockatiels do exactly
that.  Once during a short flight across a large room something in the
landing zone moved, it might have been a piece of paper blown by a fan or a
book slid off of a stack, so she (the bird) back-stepped midair and did a
hovering 90-degree turn to an alternate landing zone some few feet away. 
Amazing for a 'dash' flyer that they are.

Cheers,
Paul.
