To p51 guy!(or any other pro) What if the wing tips are far aft of the mains as it is on the DC10 and many other sweep wing aircraft,and then being caught by a sheer or downdraft in the flare.Could,t this ruin an otherwise perfectly executed wing low landing when the pilot pull back on his columm to arrest the high sinkrate? I am no pro, just asking.I have seen a tip scrape on an Md80 where there was no unusual high bank angle,but where the deck angle was higher than normal to prevent a last second high sinker.Isn,t possible to simply being caught by bad luck regardless of what happend during certification?
