A few months back when flying LH from ORD to FRA, the FA asked while we were still on the ground if any doctors are available onboard as one of the pax is not feeling well.

Being a doctor myself, I volunteered for standby. However, I've never encountered a ME at 36000ft before, and I have to say, quite honestly, I was a bit nervous.

For the first 15 minutes of our flight, I kept telling myself that I've done this before, just not at 36000ft, it shouldn't be that much of a difference... remember what you learned in med school, just relax... etc..

Thank God the pax was alright and fell asleep most of the time, and we landed w/o any complications.

Sometimes, I do think that we need to run some drills like this in co-op with airlines.
