Sorry, but you're the one who may just need a little straightening out!
Concorde, Trident (HS121) and DC-8 were three types that could use reverse thrust in the air.
I have used reverse thrust in the air many times over the years, and whilst the approval to use reverse thrust in the air may be an unusual feature, that exists on only a few types, on those aircraft for which its use is approved, it is both a safe and useful feature, with none of the problems that some would have you believe.
The use of reverse thrust in flight on a type where it is not approved
, is a completely different matter, and is about as stupid an action as is possible in aviation.
Should you survive, you deserve all that's coming to you.
