What if the next time the CPT is incapacitated for any reason? Is his stress level going to be lower than this time? I don't think so. Will A flight attendant land the plane? Again. I don't think so.
This is not about the total amount of hours of anything like that. I think pretty much everyone had his "oh ****" moment, even during training, but we didn't freeze and we just kept flying the aircraft. As pilots there is a small number of things we're not allowed to do, and one of these is for sure freezing while doing our job.
I truly hope he fully recovered from his condition, otherwise I'd consider him as an additional threat to safety.
