BEagle,
After my last hasty reply on this subject I was forced to go and dig out my old VC-10 manuals, and " whoops" I could not find any safety system which prevents you you selecting reverse in the air on the VC-10, so I have to apologize for my previous incorrect answer. My only excuse is that it was along time ago now that I was on VC-10s ( in fact 28 years ) , and I think I was mixing it up with another aircraft.
