In 1993, the space shuttle Discovery was unexpectedly diverted to land at Montgomery Field in San Diego, leading to significant traffic congestion as thousands rushed to witness the event. The announcement was made by Dave Rickards, a local deejay, causing a surge in commuters towards the landing site. The discussion also touches on humorous pranks from a high school, including a fake real estate sign that sparked numerous inquiries and a sign announcing the acceptance of boys at an all-girls school, which upset the administration. Additionally, there is a mention of a blog discussing powdered water and its implications in a scientific context. Overall, the thread combines nostalgia for local events with lighthearted school pranks and scientific commentary.
