Ugh, insomnia is a bitch...
The only confusion is your attempt at confusing the issue - the Flight Recorder (which you referred to it several times as) or FDR is a separate entity from the CVR.
Not at all - I'm saying that I don't have pictures of the entire scene as it was before anyone got there... again, this is a good case for sitting and waiting for the professionals to finish gathering up the parts and put the wreckage together (you know, actual forensic analysis, rather than armchair theories)
Yes, you did... and I quoted:
Now, unless you are having some serious issues with math... 900 KPH is half again 600 KPH...
Okay, let me take you by the hand and walk you through this...
Kinetic Energy (joules) = .5m*V^2
Where m = mass of the object (in KG)
V = Velocity (in meters per second)
Mass of an A320 is roughly 83,000 kg... if it is travelling 600 kph (approx 167 m/s), we get .5*83000 * 167^2 = 1,157,393,500 joules... which works out to about 853,649,637 ft-lb of pressure... or nearly 250 kg of tnt...
That is a lot of energy... have you ever seen a 250 kg bomb go off? For comparison:
Now, granted, they use just over 350 kg of explosives... but as you can see, there is very little left of that cement truck, aside from the engine block (which was about as far from the center of the blast as you could get, all things considered).
