Those of us retired pilots and CC who wish to break the strike can VOLUNTEER
While I'm sure it would be entertaining to see our flights manned by volunteers and retired staff (with the new retirement age it will be soon anyway) theres the small matter of airside passes which you seem to have overlooked. Takes about 3 months to get our new crew through their CRB checks which means BA can't take you up on your kind offer.
I have this vision of a line of Zimmer frames stacked in the forward wardrobe that I can't shake out of my head now.
