		<description><![CDATA[I do not see how this page can claim &lt;i&gt;Stealth&lt;/i&gt; is &quot;free of gaping plot holes&quot;. Plot holes and technical errors abound. 

The aircraft supposed accelerates from mach 1 to mach 2 in 2 seconds and from mach 1 to mach 4 in 7 seconds. A peak acceleration of 165 m/s/s (16.8 g) requiring over 23000 kN thrust, being a mere 2100 times more powerful than an F-15 powerplant and using somewhere in the order of 11 GW, or 4 times as much power as produced by all the hydroelectric dams in Greece or about 2/5 of all the power produced by Canada&#039;s second largest power company. All this from one little plane.

The planes fly from wherever they are launched to Tajikistan. Jessica Biel&#039;s plane then flies over 2400 nautical miles to North Korea in only a few minutes without refuelling . This is despite having already flown into combat and not carrying any external fuel tanks. Combat radius is more likely to be around 600 NM for a total range of 1200 NM.  Let&#039;s ignore that she flies at least 2100 NM over hostile Chinese airspace.

The other guy&#039;s plane flies over 3000 NM from Russia to Alaska. Aside from refuelling issues, most of this is over Russian airspace and it is only challenged once by 3 Su-27 fighters. A big deal is made out of it approaching Russian airspace from Tajikistan, not mentioning that he had to fly over Kyrgyzstan and/or Uzbekistan then Kazakhstan for at least 700 NM before reaching Russia.

That the plane does refuel from a flying airship says that a giant USA gasbag is stationed over one of these afore mentioned countries former USSR countries.

The EDI refuels itself by blowing the nozzle off a hose, yet the pump valve is located at the other end of the hose closest to the fuel tank so fuel would not have escaped. Tankers refuel aircraft when flying in a straight line, not constant matching of rate of turn when circling so no ring of fire would have existed.

In the opening scene of the film, two ground launched sidewinder missiles are fired at Biel&#039;s plane. They travel at mach 2.5. Given that they barely caught up to her over their 17 second flight time (travelling 14 km which is, thank God, inside their 18 km range) she must have been travelling only slightly slower than mach 2.5 or somewhere around 800 m/s all the while performing combat manoeuvres for a ground attack while engaged in nap of the earth flying.

The EDI plane also spends it&#039;s time flying in the troposphere so any claims that it could traverse the earth in 90 minutes are spurious in relation to the film, especially as a substantial amount of time is spent at a height of 15 feet.

Somehow, the EDI plane, having flown from Tajikistan to Russia to Alaska then flies a further at least 2700 NM from Alaska to North Korea without having refuelled since the airship. At least 5700 NM and it had the intent to travel back to friendly airspace.  An insanely huge distance.  All these flights take inordinately short times.

An apparently burgeoning romantic relationship between the two main lieutenants is wrongly claimed to be inappropriate.  Fraternisation occurs between officers and enlisted, not between officers and other officers.]]></description>
