Federal registration records confirm that a 2004 fixed wing, single-engine Cirrus SR-22 owned by the reality television family arrived in Illinois shortly after 8:11 p.m. on Christmas Eve. The eldest Duggar sibling is said to have checked into Reformers Unanimous, a faith-based rehab center, this summer after confessing he had been unfaithful to his wife, Anna. Josh also said he developed an addiction to pornography. A source close to the Duggars recently told PEOPLE that Josh would likely remain at Reformers over the Christmas holiday, despite having four children at home who “miss their daddy.” Thursday’s private flight to Illinois could mean relatives are visiting with Josh for Christmas. A representative for the Duggars did not respond to requests for comment. Josh’s most recent scandal has been featured on his sisters’ new TLC special Jill & Jessa: Counting On, which airs Sundays on the network. On the show, some of Josh’s 18 siblings weighed in on how much the cheating revelations hurt them and the family. According to a source, Anna took youngest daughter Meredith Grace to see her dad a month ago, with Josh’s younger brother John-David, a pilot, flying them out on the family’s private plane.
