SSS, I've no idea why, but then I wasn't flying the aircraft. I think the pilot sensibly opted to concentrate on putting it down due to the low altitude at which it happened. It was flown out again once the issue was resolved.
I'm unsure why you seem so concerned why some aircraft were designed and built with a different system to the ones you have flown. It's simply a matter of learning a new technique and understanding why it's done the way it is on a new type. As I've said twice, there is no key on the type I flew for some years, just a rotary switch.
