When you say "collided" it makes it sound like they had a head on collision. However I am betting that they were flying in formation, and got a
little too close and bumped into each other.
I hope that the pilot in the lost jet ejected in time and survived.
A pilot is worth far more than a old hunk of metal any day.
Hopefully it wrecked in an unpopulated area and things turn out OK for everyone involved.
Thanks for the news.
