Years ago I saw a video of Boeing testing the 747, specifically its no flare landing capability. From the far end of the runway a camera filmed a 747 arriving at some truly scary descent rate - God knows how many feet per minute. On 'touchdown' (more like impact) the wings flexed, the engines shook on their pylons, and the aircraft looked like it had enough inertia to dig a big hole in the runway. But the gear held together. Mr. Boeing certainly builds 'em tough.
One of our engineers told me recently that what they regarded as a hard landing would to me feel like a crash. I believed him.
