Huh? The mass of the A380 is at least 100 (and perhaps 1000) times the mass of the F16 (just picture them flying side-by-side and note the area of sky obscured by the A380 versus the F16 and note that although the mass density of the F16 might be higher than the A380 because much more of the mass is engine, it is not twice as dense as the A380).

And no way can the F16 go 10 times as fast as the A380.

So the kinetic energy of the A380 is definitely higher, probably by a considerable amount.



Weight (Maximum take off)

  A380 = 569000 kg [1]

  F-16 = 19200 kg [2]
Top Speed

  A380 = 945 km/h = 262.5 m / s

  F-16 =  2410 km/h = 669.444444 m / s
Kinetic Energy

  E = 0.5 * m * (v^2)

  E380 = 0.5 * 569000* (262.5^2) = 19 603 828 125

  EF16 = 0.5 * 19200 * (669.444444^2) = 4.30229629 × 10^9

That said I think it probably doesn't matter. On impact the plane would breakup and you probably wouldn't get full force from either and also I bet it was built with more then a factor of 10 safety factor.
