Beat up?
I don't think so.
These were two highly capable individuals embarking on a one hour flight with one carer between them.
As someone who works on the other side of the flight deck door I can assure you that these people are more often than not, both fiercely independent and capable of managing their disability, on or off the aircraft.
They had an able bodied person to assist with bathroom visits if needed on this one hour flight.
Cretinous really that they weren't allowed to fly given the circumstances.
