Discontinuity, Plot Holes, Errors With "The End of Time (Part 2)" Story
In this story, the Doctor has to open one door in the radiation chamber to open the other door to help his companion, Wilf, who is trapped inside. Because the machine is malfunctioning, it essentially kills the Doctor. (But not immediately.) In the footage as Wilf is talking to the Doctor while trapped, there is clearly a huge gap seperating the side of the glass door with the rest of the cubicle, meaning the door could in fact be easily opened.
maybe there was glass so pure in the space that you couldn't see it.
