In the first episode, the drone breaks through the glass dome covering the dig site, creating a fairly large hole. When Col. O'Neill lands, it is only just over seven minutes after it made the hole (since O'Neill comes straight out of the elevator and everyone asks how he made it, it cant be much later, and it was announced that he was seven minutes away) but in the aerial shot of the compound (which is the same angle as the one showing the drone blowing the hole in the roof), no hole is visible. No way they managed to get to the center of the roof and repair it without any visible trace that quickly. Hole being made is @ 5:47, shot of roof sans hole is @ 8:14
