There are many programs that Parishes can sponsor for Returning Catholics.
Landings is only one of them, and it didn’t fly in our vicariate at all.
My church has the most successful one “Catholics Can Come Home Again.” (Also the name of a book by Carrie Kemp.)
I helped when it first got started because I was so angry at God for taking my husband at the age of 48 and leaving me with five children, ages 9-19 to raise. Thank goodness for the Grace of God and a grief recovery program that kept me trucking ahead, rather than stopping completely.
