There was a USAF F-4 ejection over the Gulf of Mexico in the mid-1970's where the student in the front seat initiated the ejection sequence. The canopy jettisoned and the back seat had some sort of malfunction and did not fire. The front seat went out leaving the instructor sitting in back with a loud but flyable NORDO aircraft which he successfully took into Navy Corpus Christi after making a pass to clear the training pattern of TS-2A's.
He dropped the hook and took the arresting gear and then gingerly climbed out of the plane with minor flash burns from the front seat activation. The plane was left on the runway for a couple of days until Air Force 'Egress Systems Specialists' could arrive and safe the half-cocked seat.
Here's an earlier F-4 with battle damage that sent the WSO out. The pilot decided to stay onboard and land the aircraft.
