I have to say I’m not buying the oleo extension explanation. First off, the struts have dampers. The purpose of dampers is to prevent rapid compression or extension of the struts. Second, suspension systems tend to have bump rubbers at the end of their travel to prevent the stress of metal to metal contact when the struts hit either the full extension or the full compression stops. These would reduce any potential ‘bang’ to a jolt.
And even if you had landing gear struts without dampers, the aircraft does not come off the runway instantaneously. The gear struts would extend at the same rate as the rate at which aircraft lifts off the runway. Is that fast enough to cause a bang at the moment when the wheels leave the tarmac? Tilting bogies would also soften the process.
On the other hand, I have been running landing gears up and down and heard (and felt!) very noticeable bangs - from the landing gear doors. In fact, with one aircraft you couldn’t run the gear at full speed or it’d jump off the jacks. This has been fighters, but with the big gear doors on commercial aircraft the velocity of the edge of the door farthest from the hinges will be quite high, if you want the gear doors to close at any noticeable rate.
I’m not sure here, been a while since I got close and personal with a 737 - but don’t they still have gear doors? They just don’t cover the wheels themselves.
I’ll bow down to conclusive technical evidence, but I am not convinced yet.
I thought I was doing good trying to avoid those airport hotels... and look at me now.
