I too hope for a complete recovery for 19/K (known to many people simply as "Papa").
Meantime, his son, Dinan, has been flying extremely well and has been making good landings. He has been all over the Capitol building, and has been exploring the surrounding area, watched over closely by his Mom, Alley. This morning he headed for a hotel, with Alley in hot pursuit.
Dinan has also flown back to the nest box, and a couple of nights ago, stayed there for the night.
There are some great people on the ground in Lincoln spending long hours watching out for him.
I hope he will be around for a while, so that his Dad will be able to see him fly.
