I doubt it. Droping an airborne unit in the night close to a big town just begs for disaster. St Mere Eglise, anyone? And that was just a village. So you have to drop them farther. Also, paratroopers need time to get together after landing and organize before they become a significant force. In Normandy they had serious problems with that. Germans would have had time to consolidate their defense.
Special forces? They may have captured the port itself, although I'm not so sure. How would they get there? A raid, St. Nazaire style? But how long would they have been able to hold the port?
