Qantas Airways once powered an interstate flight on cooking oil. This marked Australia’s first commercial flight using sustainably derived biofuel.
100 Mind-Blowing Qantas Facts
Because astronomical time and atomic time don’t always line up, every so often, we get a leap second. Earth’s spin speed can be a bit unpredictable. Atmospheric winds, Northern Hemisphere winters with heavy snow, and other big weather systems can affect how fast the planet rotates. To keep the difference between astronomical time and atomic time to less than .9 seconds, the International Earth Rotation and Reference Systems Service will occasionally announce the need for a leap second. Most people won’t notice a leap second, but they can be a huge pain for tech companies. Because leap seconds are added irregularly, developers have no way of working them into their codes, which has caused websites like LinkedIn and Reddit to crash in the past. A bug caused by 2012’s leap second created so much chaos on Qantas’s servers, more than 400 flights wound up being delayed.
