I am still wondering why they simply could not target this whole thing with the Phasers of the Enterprise and then shoot it down...

Then the Enterprise would have been blown apart in no time, then the Narada would have lowered another drill, thus being counter-productive.

A more apt question is why the Enterprise didn't beam the Genesis device from the Reliant instead of just firing on the Reliant and risk detonating the Genesis device.

Whats the average skydive height?

I have sky dived from 10,000 feet before.  Thats a typical height. I know others who have sky dived from higher altitudes. I would have to ask them what the height was though.

Ya know... This really is rather humorous...

Of all the science complaints I had/have about STXI, I don't see this as all that much of a problem. They jumped with helmets and didn't need them once they reached the platform. Even with the thinner air at the altitude it would take a period of time before their muscles would be feeling detrimental effects for lack of oxygen. How long did that scene last? How long can a healthy, non-smoker hold their breath? Even with the thinner air at altitude there was still some oxygen.

Exactly. I think this is really no big deal. They did jump with helmets on and then took them off. It really is a non issue which is why I refuse to debate the issue further. I think there are more important factors of the movie to debate.

As we can see in this article 20,000 ft above the surface is well within the survivability of an average human:

How high do skydivers usually exit?

12,500 feet AGL (Above Ground Level), sometimes up to 14,500 depending on the altitude of the drop zone, type of aircraft and type of jump. ¿From these altitudes, at a typical belly-to-earth fall rate of around 115 mph, a skydiver can enjoy a freefall of up to and slightly over 1 minute until he or she reaches pull altitude. ¿This time frame shrinks considerably if the skydiver falls in a vertical head-down position (a popular form of freefall called "Freeflying"), or expands to around double that number if the skydiver is wearing, and properly using, a "wing suit" which can nearly halve freefall speeds.

Some exceptions to these maximum exit altitudes:

¿ ¿* Large freefall formations (say, around 100 or more skydivers) require more time to build (form-up in freefall), thus such jumps start at higher altitudes and often require that jumpers breathe bottled oxygen during the climb to the higher altitudes (around 18,000 feet is typical).

¿ ¿* High altitude jumps made for the sake of making a high altitude jump. ¿Some skydive centers offer high altitude jump training for experienced jumpers. ¿Such jumps can approach 30,000 feet. ¿During such jumps, skydivers must carry & use bottled oxygen ("bailout bottle") in freefall. ¿ Basically, a high altitude jump is a feather some skydivers want in their cap.

What's the highest parachute jump ever made?

Currently this record* is 102,800 feet (around 20 miles). ¿(These days it seems there's always a few teams preparing to beat the record. So keep googling around the internet to see if any of them finally beat it. One day, somebody will.)

This successful 102,800 foot Air Force test jump was made, from a special high altitude balloon, on August 16, 1960 by Capt. Joseph Kittenger. ¿He was in freefall** for nearly five minutes.

Because of the extreme altitudes involved, Joe had to wear an astronaut-style pressure-suit. ¿Keep in mind: the world's first human astronaut, Yuri Gargarin, had not yet flown into space. Only military test pilots had exceeded 100,000 feet of altitude in experimental rocket aircraft. Joe was making a parachute jump from the edge of space. Also, at those altitudes the air was so thin, and the resultant aerodynamic drag so small, that Joe approached the speed of sound in freefall (he was clocked at around 614mph -- there is some debate that he might have even surpassed the speed of sound. But I don't think the data supports that claim).

Don't forget, the summit of Mount Everest is 29,029 feet.

Right we think too much alike!! LOL

The drilling platform is only at 20,000 feet so its well withing human safety standards provided one is in good health.

;)

Is there a reference for that 20,000 feet for the drilling platform? If so, this was dead before it began...
The height of the platform is in the novelization but not stated in the movie. But going from that height yes the issue was dead before it started.

Needless to say that this dude needed a whole mess of equipment and he didnt just jump with no helmet on ........

Let it go. You're a winner. You don't need to continue obsessing over being right. You're always right, so sleep well tonight my friend.

OK so they just froze to death.
Now what!

They were wearing jumpsuits. They were probably insulated.
