I'm cabin crew on the 767-300ER, and i often sit at doors 3 (above the gear) for takeoff/landing.
It does have an unusually large 'thump' on landing, and many pilots have said it IS
because of the forward tiliting gear.
As the front gear touches, it brings the rear tyres down very rapidly behind it!
I have witnessed ceiling panels come down on a couple of occasions and even the odd O2 mask!!
Strangely , if you sin the flight deck for landing , the sensation is quite the opposite!
The noise and 'touchdown' seem to be completely 'soaked up' by the long fuselage and even a hardish landing feels very soft up front.
From this point of view , it may be hard for the flight crew to use their senses to determine how good/bad their landing was!!
We took it into Aberdeen one night , very foggy, full load, small runway with terrain - that was a hell of a thump
