In the EI-DON landing last year the pilots did not even realize something was amiss until they saw they couldn't taxi under their own power anymore
That's not true. From the crash report:
'The crew of a KD Avia Boeing 737-300, registration EI-DON declared emergency after an unsafe gear indication. A low pass confirmed that the gear was not deployed.'
