The following is a possible concise summary of the text:
The text is a transcript of a video that explains two near-collisions between airplanes at airports in the US. The first one happened in 2022 at San Francisco, when an Air Canada flight almost landed on a taxiway where four other planes were waiting. The second one happened in 2023 at Austin, when a FedEx flight had to abort its landing because a Southwest plane was taking off on the same runway. The video analyzes the causes and consequences of these incidents, and compares them to the worst aviation accident in history, which occurred in 1977 at Tenerife, when two Boeing 747s collided on the runway. The video also mentions other runway incursions that happened in 2023, and suggests some safety improvements for airport operations. The video is part of a Nebula original series called Under Exposure, which explores topics that are not suitable for YouTube.
