You can see that truck-mounted stairs were used to gain access to the cabin (I assume no suitable jetbridge was available.) I have a question: how do you get a passenger on a stretcher down those stairs? (I assume that since the pax was airlifted to hospital, he would have been in no condition to walk down the stairs.)
When I did first aid, I was once called out to stretcher out a spectator at a sports even who'd fallen down some stairs ... there were four of us on the stretcher, and we still struggled with the stairs -- and they were nowhere near as steep as the stairs in the picture.
The EMT at the lead of the stretcher would almost be holding it over his/her head in order to keep the patient more or less level, or those at the rear would be bent double. Could/would a scissor-lift (cargo loader) be used?
