"not much you can do to hide a lower leg amputation when you're sitting across the table from someone."
Matt: Most people wouldn't notice.
Most company websites would state "must hold a valid JAA Class 1 medical" on criteria for employment.
As our friend has been given the all clear for the Class 1, it is suffice to say that the medical professionals at Gatwick feel that his amputation is not a factor for flight.
If the candidate is mobile and can get themselves off of a plane in an evacuation situation then he is perfectly capable of doing the job.
I really don't see it being an issue for any airline. It really makes no difference to flight performance.
Hats off to our friend! Good luck and I hope you will come back on here in 18 months with your right hand seat.
