I've noticed in various pics of the President's pimped 747s that the engine nacelles appear to be a bit longer than usual for those donks...no idea why myself, any takers?

Bullethead - I spent time during my younger years visiting that base when on Vacation to the south in NZCH, the Navy VXE-6 blokes were top guys but the USAF personal were always super-serious and edgy.
There have been some interesting odd-ball USAF aircraft (mostly C-130 variants) visit NZ on the sly and stories abound as to what they were up to, however I won't post any I've heard for fear of talking cr*p but perhaps there are some ATCs out there who may have some ideas? Apparently the NZ government cooperates with the US military more than the general population realize.
