there was never any doubt that she'd fit OK.
Folks,
Have a look at Wellington, NZ, and we flew B747SP in/out of there for years, usually in very "interesting" winds. Give or take a couple of meters, the length is the same.
The takeoff and landing performance of a B747-200/200/400 is better than an SP, if you had a copy of the landing field length graphs, for the weight they were at, you might be surprised how little was required.
Tootle pip!!
