The squall is said to move at ~230mph. This is far less than the sound barrier in air, much, much less than in water.

Bozola,
Thanks for the link to the ‘squall' I have been looking for that article for awhile. I must have read about that ‘600mph' torpedo in a newspaper article, I can't find it anywhere, so I'll stop repeating it.
“However, this bubble is at pressure equilibrium, while a vacuum would not be, unless it was an extremely hot near-vacuum.” ---Ipetrich
I was referring to the highly speculative ‘micro-warp drive'. Theoretically the interior volume of a region of space bounded by a closed surface, because of space curvature, can be made much larger than the flat-space volume bounded by its surface.
That is, the application of general relativity to create a volume of space that is larger on the inside than it is on the outside. And perhaps use that ‘bubble' to travel forward form point A to point B 100 times the velocity of light is very appealing however the energy requirements, guidance systems, loading / unloading {how do you keep the ‘bubble' from bursting} are practically insurmountable.
“Alcubierre's metric uses an analogous expansion of space to drive the warp bubble forward. However, since the ship within the bubble is at rest in its local space, the occupants will feel no acceleration forces when the forward speed of the bubble changes, nor will they experience the "usual" relativistic effects of mass increase and time dilation. If an Alcubierre warp-drive ship travels 100 light years at 100 times the velocity of light, to both the occupants and outside observers the trip takes one year, no more and no less.” ---John G. Cramer
One of my favorite websites, click on ‘table of contents', at the top, to find a lot more articles. ‘What we don't know' and the “Rare Earth” hypothesis are two of my favorites.

Micro-warp drive might be able to work.
It all depends on Quantum Gravity.
Maybe it will let us do it, or maybe not (I hope the later).
Radioactive GM Crops.
Slightly above background.
Safe to eat.
But no activist would dare rip it out.
As they think it gives them cancer. |

Very interesting line of discussion!
My two cents would be that UFOs were invented by bored children (or bored child-like adults) with frisbees and cameras and wild imaginations. Later on, UFOs were just the result of wild imaginations about celestial objects which were, indeed, *unidentified*. With the amount of light pollution, identification of anything would be difficult, and misconceptions, combined with mental aberrations, could result from pre-senile minds.

IMO, that's excessively condescending. The large majority of UFO sightings are of known phenomena; the planet Venus is a big favorite. You must realize that celestial objects don't come with name tags on them; Venus looks like a very bright star.
Ipetrich:
It is great fun to condescend. Then one can condescend to condescension, and a chain of ad hominems (ad feminems?) can ensue. Whatever. It is such fun.
