I was think about some route that used to be flown by 747sp/200/300, but are now flown by 747 400. A lot of these routes pushed these model of Boeing 747 to full power take off. For example when NZ flew there LAX-ACK routes with 747 200B, the 747 219 would shake the widows and floors in the terminal as they past by on there take of rolls. They also use almost all of LAX longest runway, and it look like it took for ever for them to climb( 747 classic are slow climbers). I know UA, NW, JA and ANA used 747 200B on the JFK-NRT and I know they had to have some powerful take off. So what is the most powerful take off you ever seen?
PS: By powerful I mean loud and body shaking take off.
