Aging B-1 Bomber May Soon Have to Restrict the Way it Flies

Interesting article but conflicts with other articles I've seen that say the constant high altitude missions are causing excessive wear on wing pivot points. As this article says the B-1 was designed to fly with low and fast with its wings swept back. The long at altitude missions with wings swept forward seen in the Middle East have caused wear that wasn't intended in the aircraft design. Either way, my last aircraft seems destined to restrictions.
