The Space Shuttle is flying again with STS-26! Let's see if we can figure out how to fold some chairs.

We take a quick break from the main narrative to take a look around at a few things that happened during the shuttle's lengthy hiatus.

In this lengthy supplemental, we listen to Allan McDonald's testimony in front of the Rogers Commission on February 25th, 1986. This is a long episode, so just a friendly reminder that supplementals are considered optional!

We conclude our coverage of the Challenger accident by digging into why it was able to happen.

We look at what physically happened on STS-51L and try to answer some questions.

Before we deal with the tragic loss of Space Shuttle Challenger, we take a moment to learn about the remarkable mission that should have been.

Columbia is back after a long stint in the shop, but there seems to be some trouble getting off the launchpad.

Atlantis is back already with a bunch of satellites and an investigation into on-orbit construction of large structures.

In this supplemental we'll listen to the actual mission audio as Apollo 13's oxygen tank explodes. We'll hear mission control discuss stirring the tanks, Gene Kranz quickly mention the LM lifeboat concept, and several famous utterances from spaceflight history.

Spacelab is back with a flight sponsored by West Germany! I apologize in advance to any German-speaking listeners who have to endure my pronunciation.
