Nothing beats a full power brakes on departure.
Always remember flying as a pax the week BA 757's took over from Tridents to BFS. Crew held it on LHR's 28L, spooled it right up to full power, held it and let go. Every pax jammed into the back of the seat - brilliant. We were off the runway in about half the distance of a Trident and climbing like a rocket. There was a real WOW factor in the cabin from the regular shuttle passengers.
One other time I remember it happening was on a fully loaded Singapore 747-400 out of LHR on a hot summers evening. Spooled up and held brakes on at end of 09R. Even with that it came off very slow with everthing shaking - Hatton Cross station passing very close under the wing! Got the impression weight and balance might have been a tad out.
Had a cockpit ride in a BA 747-200 out of LHR 09R. (pre 9/11 - those were the days) Crew did a rolling take-off and adjusted the SID (a little bit) so we passed my parents house!
