Best Jet of WW2?

[plan_D]

Yes, but I did actually say not with altitude. Speed of sound wouldn't change in a vacuum. The only reason it changes because of altitude in the atmosphere is because the air particles density changes.

no, the speed of light mener changes....................

mener

is that supposed to say...never?

[plan_D]

Lanc do you ever listen in class? Ask your Physics teacher, the speed of light does change that's why it refracts.

[cheddar cheese]

i thought so

[brad]

Mach one's about 760mph.............

the speed of sound is only 630 my teacher told me so nereand he has flown at mach2 and that was 1260

the speed of light does change that's why it refracts.

no, refraction is all to do with the angle of incidence..............

The speed of sound changes with altitude. It may be 630 higher up, but Plan_D is rigth about the lower altitudes.

[brad]

i guess im not the only won who cant spell

[cheddar cheese]

everyone makes mistakes, some a little more than others

[Lightning Guy]

Sorry, but my education isn't in language (and certainly not spelling).

[cheddar cheese]

ive only seen you make a couple of mistakes, i think brad was referring to the lancs strange spelling of "never"

[the lancaster kicks ass]

how do you know i didn't mean to say mener?

[plan_D]

The speed of sound is 760 mph at sea level, my dad was an aircraft technician for 24 years, he knows what he is talking about. Plus the fact, I already knew it was anyway.

The speed of light changes when it goes through a different medium, it goes slower through water than air, and slower through glass than air. The angle of which the light enters the glass decides which angle it will come out at.
At 46 degrees and above it is total internal reflection which reflects the light instead of refracting, the light still changes speed. Ask your teacher.

back to the original post I would have to say because of it's combat experience, the Me 262A-1a. Especially in the night fighter role with Kommando Welter. Nothing could touch it at night ! Though almost unknown in this role it may well have been the finest short range night fighter of the war...............
