Reminds me of an incident in Barbados many years ago. A PanAm Tri-Star doing a 2 engine ferry had a problem with another engine very shortly after liftoff. He announced engine failure, declared an emergency, and his intention to return immediately as well as commencing fuel dump.
When ATC started complicated radar vector instructions, the aircraft announced curtly you don't understand, we are returning NOW, have the equipment standing by!
They did a very tight circuit, dumping fuel almost to touchdown.
