Plot hole: After the six shuttles take off, there are obviously dozens, if not hundreds of Drax' minions left behind in the base. Not regular employees, but the kind that knows what's coming, if only because Drax is obviously talking about it, e.g. to Bond, quite openly. Would they just stoically stay behind to be gassed? One would think they would mutiny and rush the shuttles wouldn't one?
Plot hole: The British government sends its best agent to the headquarters responsible for a missing shuttle, and Drax immediately wants to kill the man sent to talk to him. Surely Drax would have been smart enough to know if he had Bond killed both the American and British governments would have investigated him, even if he could chalk up Bond's death as an accident.
Continuity mistake: When Drax throws two pieces of meat at his Doberman Pinschers, one piece lands by the leg of one of the dogs. But when Drax clicks his fingers to signal the dogs to eat the meat, the piece has moved in front of the dog's face.
Stupidity: After Corinne Dufour realises that Drax intends to have his dogs kill her, she inexplicably attempts to flee on foot, running right past the golf cart she arrived in. The golf cart would have given her more speed, range and protection, and would have been a much better choice for fleeing.
