Which has a higher kinetic energy?

An airplane traveling at the speed of sound or an airplane with half the weight of plane one and traveling at 2 times the speed of sound?

2. Relevant equations

KE = 1/2 mv^2

v=gt

3. The attempt at a solution

I think I am just get mixed up on words. If they were the same weight the plane going twice as fast would have 4 times the kinetic energy. (v=2^2=4).

I think I am going the wrong direction. Would their kinetic energy be the same? Since plane two weight is half but double the speed. Help
