I heard they did not descend as well. Hopefully, a link will emerge. If true, these guys are toast.
The Brazilian daily O Globo reported Tuesday that the pilots of the Legacy, which was carrying seven Americans, allegedly disobeyed an order by the control tower to descend to a lower altitude just before coming into contact with Gol Airlines Flight 1907 last Friday.
The paper said the Legacy flew at 37,000 feet to the capital Brasilia, but then ignored an order to descend to 36,000 feet to continue its flight to the Amazon city of Manaus.
