Reminds me of the Douglas DC-8, which had a lift spoiler that, incredibly, could be deployed before the aircraft's weight was on the undercarriage, leading to one major tragedy when a miscommunication between capt. and 1st. off. resulted in the latter pulling the lever when they were still some 200 ft. up. Idiotically, Douglas's only effort to prevent inadvertent activation was a sign by the lever DEPLOYMENT IN FLIGHT PROHIBITED, which one pilot said was as much use as "crashing this aircraft is prohibited."
Douglas had some strange mechanical anomalies, the worst, of course, being the cargo door latching on the DC-10, which resulted in a very close call in Canada and, of course, the first crash of a fully-loaded jumbo jet, Turkish Airlines in Ermenonville, France.
