Are planes safe during COVID?

I look forward to watching you as my physics teacher.
Recently while studying about momentum, a question arose in my mind. It is as follows:
If a truck of mass 1000 kg travelling with a velocity of 5 m/s hits a truck of mass 500 kg travelling with a velocity of 10 m/s in the opposite direction, which truck will be harmed more as a result of the collision?
We know that a body possessing greater momentum causes more harm than the one possessing lesser momentum. But here the momentums are same. So on which of the trucks more harm would be produced?
I hope I get my answer soon.

Anyone can answer if that person thinks he or she might know it.
