Two very blog-worthy things today:
First, SpaceX continues to wow with their latest flight and intentional return to earth of their Grasshopper test vehicle. The flight profile reminds me of the early rocket videos that suffered from pogo oscillation. I do NOT recommend the following experiment if you wish to experience this yourself:
- Sit in a running car in an area free from obstacles.
- Ease off of the brake/clutch so the car is rolling along at idle.
- Pull the lever for your seat forward-back release. (Electric adjust need not apply.)
- Gently press the gas pedal.
Anyhow, check out their fun video, which will explain the title reference above. Make sure to look closely at 1:14 and it will all make sense.
Update: And now, with an actual link to the video!
