international hog driver
speaks for many of us.
from the reporters account and the early speculation by the inspector , it would seem that the GOL 737 may have taken evasive action at the last microsecond
it is also apparent that it was head on, that an offset would have saved them, that being 100' up or down might have saved them.
The question now is: why were two planes on IFR clearances not seperated by customary altitude/direction of flight rules?
Is it a mechanical problem, an altimeter miss set? it does happen
an improper clearance, no radar monitoring of altitude?
a misunderstood clearance?
as I mentioned before, a movie of the 50's or 60's, called, "THE CROWDED SKY" aslo a book by the same name, covered exactly this type of collision and how altimetry, communication and human factors resulted in a mid air.
