Continuity mistake: When Bond leaves the Aston Martin on the mountain its roof and rear window are covered in snow. Right before it explodes the snow is gone.
Revealing mistake: When Bond drives on the frozen lake, there are mounts of snow to hide the explosives from the rockets fired at by the enemies.
Continuity mistake: Before Bond lands on the yacht his parachute is burning and noticeable holes are made. A shot later the parachute looks perfect, except for a couple of steam clouds coming out.
Continuity mistake: When the imposter crashes against the barrier, the jeep blows away the right side, but it reappears a shot later. (00:05:11)
Continuity mistake: At the Bratislava hotel, the sheets are rolled up covering the pillow. When Bond is placing the bullets inside the charger, the sheets are suddenly folded differently.
Continuity mistake: At the Bratislava hotel, Bond puts on the black glove in his hand, closes it in a fist, but from the immediate angle his hand is open, and he's closing it in a fist again.
Continuity mistake: When the car cuts the large hole in the ice Bond doesn't move when he finishes the cutting the circle, but we see the view from his car, and he's several feet away. Also the size of the circle he cut out dramatically changes to being a lot smaller.
Factual error: When James Bond and Kara Milovy are on the plane and it runs out of fuel, one engine quits first. When this happens, the aircraft turns towards the stalled engine, so the pilot has to compensate by steering towards the good one, or the plane will spiral. James Bond doesn't do this, he just keeps the wheel straight and pilots normally. (01:59:17)
Continuity mistake: When Bond stops the timer on the bomb in the transport plane, the digital readout shows 3 seconds to detonation. When he restarts the timer to explode the bomb on the bridge below, the time to detonation has rather conveniently changed to 9 seconds. This gives the bomb time to land on the deck before it explodes.
Continuity mistake: When Bond and Milova escape Bratislava it is snowy and wintry. When they arrive in Vienna, which is only 50 miles away and at the same latitude, it is late summer or early autumn, with signs of leaves changing.
Audio problem: When Saunders says "In the box, between the KGB minders" at the concert, his mouth is not moving.
Factual error: When Bond steals the opium laden plane from the airbase, Kamran Shah and his men are busy fighting the Russians. Considerable flying time later (during which Necros gets the boot), Bond then drops the bomb on the bridge. Somehow Kamran has managed to get ahead of the plane on horseback.
Continuity mistake: When Bond exits the tunnel in the Aston Martin they get fired upon by an armoured car - look at the scenery outside the Aston, from inside there is no left turn, but one appears out of nowhere for Bond to take and head down to the frozen lake.
Factual error: Aircraft have multiple independent tanks. If one tank is hit, it should be able to fly for hours on the others. It would be very unlikely that all tanks of the plane got hit during the firefight - some are in quite well-protected spots. It is actually very nigh impossible to pierce every single tank from the outside and still have a flyable plane remaining.
Continuity mistake: During the aerial showoff, in some shots the landing gear of the plane is extended, in some retracted.
Audio problem: Near the end of the movie when Bond cuts his shoe off to make Necros fall and Necros starts screaming you can briefly see his mouth is closed during the fall.
Continuity mistake: In the final shots of the fight on the plane, where Necros holds on to Bond's boot, his right hand position on the boot changes between shots.
Continuity mistake: When Bond and Necros are fighting on the opium packages behind the plane, in the wide shot we see that Bond is all the way at the top of the bundle of packages - he takes his knife and cuts the net near his knee. In the next wide shot we see that Bond's head is above the top of the bundle of packages, but in the next close-up, packages are dropping from above Bond's head.
Other mistake: On the frozen lake, Kara screams, "James!" but he did not mention his name.
Other mistake: When the tyre gets blown off the wheel rim during the chase we see no mechanical workings for the spikes that appear in the next shot before Bond drives off, we see only a tyre coming off, and we assume for maximum grip that all wheels would be fitted with spikes.
Chosen answer: She could have been let go off screen once it was clear that Bond wasn't going to kill Pushkin, so they could formulate the plan in secret.
