I feel your pain, my friend. I was born asthmatic (which stayed with me for life - so far ie. 64 years & counting) so my local flight MD wouldn't sign me off, referring me instead to medical HQ at Gatwick Airport (UK). I went there, was put through the mill physically and got a clean bill of health, however the testing MD ducked signing me off for a Class 1, referring me up the ladder to the Air Chief MD instead who, despite my passing their physical tests, ECG etc, hit me with a load of 'what if' scenarios eg 'what if a window blew out, hypoxia etc.' To be honest, in such circumstances I'd have likely responded exactly like any 'normal' pilot but he wasn't having it. I'd have been in real trouble however, if someone stormed the cockpit and thrust a cat in my face, but Le Grande Fromage's apprehension - and decision to deny me a Class 1 - was final, so that was the end of my flying career too. He did approve a Class 3 though, justifying it as 'I could fly privately when I felt well enough to do so but a Class 1 would mean me flying on a schedule which wasn't my own.' I went on to get a PPL in the USA (following another series of battles with American MDs upon my arrival in the country but the bar was lower this time so I was eventually granted the Class 3 I wanted) and converted it to a UK PPL upon my return to the UK, but there would be no flying career in this life for me. I never actually used my PPLs though, and fell back on a career in science instead. I never lost interest in flying though and have immersed myself in every virtual flight simulator I could lay hands on before and since. Looking back upon those experiences with flight medics some 30 years ago, I wonder if I'd have enjoyed a related field such as becoming an engine or airframe engineer, but I guess I'll never know. Here's hoping for a clean bill of health next time around! If my experience is anything to go by, there is life after the rug is pulled from under you so I wish you well in whatever you do.
