The 747 (any of them) can be sideslipped like any airplane.
I demonstrated that many times.
Just be careful with sideloads on engine pods.
Applicable warning to 707/720 and DC8, same concern applies.

The 747 is a pussy cat. Is big, yet a delight to fly.
Wish I knew the crew, know many Evergreen boys.
They are outstanding pilots, with good training standards.
