An aircraft engine thrust reverser includes a bi-fold door having a first panel pivotally attached to a nacelle and a second panel hingedly connected to the first panel. The second panel is slidingly received within a pair of tracks disposed within the nacelle. A compression link provides mechanical communication between the second panel and an efflux control assembly such that the bi-fold door is hingedly openable when slidingly urged along the tracks when the compression link responds to the efflux control assembly.
