Factual errors: In all the close-up scenes with the gas balloon the basket ropes are tight from the load ring and down, but from the load ring and up to the balloon they are slack. Had it been a real flying gas balloon, all the ropes and also the net above the load ring would have been very tight during flight since they are carrying the weight of the basket and everything in it. It is clearly visible that the lifting force, by a stage crane, is erroneously placed in the center through the appending gas valve. Had the sandbags on the basket actually contained sand, they would not have bounced around so lightly. Not to venture into details, but most of the flight behavior of the balloon is completely unnatural when compared to the behavior of a real aerostat under such circumstances.
