Hello; Within the past 8 years I filmed a few hard landings of different airplane types. In todays TOP 10 video I sumed up the heaviest landings I have ever filmed. Two of these landings were performed by Boeing 747` s at Maastricht airport. Don` t know what` s going on with the runway at Maastricht but I have seen a few hard landings at the small airport in the Netherlands. Maybe it` s the small humb near the touchdown area which makes the flare a little unpredictable. Some of these hard landings were also caused by the lack of flare in general. Check out the Airbus A321 of British which looked like the runway was just in its way during its flight. There was no flare at all. By definition an hard-landing equals or goes over 2.1G. This landings are "soft - hard". The Antonov 124 nose gears are remarkably strong, because landing like that can immediately collapse the gear and together with the Bombardier landing are the most severe type for the landing gears. Tons of responsibilities on the shoulders of these pilots! Thank you pilots for doing this intensely stressful occupation. I’ve heard that flying big jets is “hours of boredom punctuated by moments of stark terror”. And after 25 plus year of professional flying, I would agree.
