There is a fair bit of misconception on this thread, and some unfounded claims. There are far more sponsership schemes available to able bodied people than there are to disabled. Generally the disabled sponserships schemes are for a few flights rather than a whole licence, as it can really bring joy and focus to lives that have been affected by a severe trauma or illness.
diabetes - they flew solo
Since when was diabetes a disability?
A significantly disabled/handicapped person would not be allowed to solo, let alone gain a licence of any sort.
Can't get much more significant than no arms
There are plenty of scholarships available to able bodied people, I have personally benefited from three such scholarships which funded around 2/3 of my PPL. Just get out there, do some research, and apply.
