Runway of 7000 ft short for a B737? I think not. In another life flying for MH in Borneo Island in the 1990s, we operated into and out of an airport called Tawau airport...TWU, WBKW which was only 4500ft. Because of two hills close to the extended centreline, the displaced threshold meant that the LDA for rwy 17 was only 4200ft with a downslope to boot! In tropical torrential rain and gusty wind conditions, it was a challenge to land a B737-400. They had Boeing short field markers painted.
If landing is not assured with the Boeing short field TDZ, a wave off or rejected landing is mandatory. Special training and qualifications required. In the years of B737-200/300/400/500 operations, no mishaps occurred. Of course, there were a few close calls, nothing disastrous until a F-50 flown by an ex-AirFarce jockey crashed overshooting the runway in a botched landing.
They have now moved to a different located with rwy 06/24 of 8800ft long.
LGA might really need a little more attention but not that difficult by any means. Maybe,
just happened.
