Very easy to do. Even though most airlines REQUIRE the localizer be dialed in, it doesn't happen. Saw it many times at ELP/Biggs (we called Biggs 22R) and Ellyson Field and Pensacola Regional. Ellyson was a helicopter base, 1500' runways, saw an Eastern 727 almost touchdown there. Ellyson is an industrial park now. Also Corpus Christie and NAS.
Fortunately it usually just hurts egos.
ICAO FHSH, Runway 02/20, 15 degrees South. VOR, GPS ground augment to ILS precision. Nice what $350m can make. Always nice to have options, especially in the middle of nowhere.
Took a P3 into Ascension for two weeks back in the '70's. Nice people, nice island, nice airport but SO remote.
