There are two different major categories of fruit. Climacterix and non-climacteric. Climacteric fruit ripen with the production of ethylene gas. Ethylene is a major plant hormone that triggers a cascade of other biochemical processes.
Bananas are climacteric so they are harvested green and stored in a cooled (13-14C) containers with an absorbent to remove ethylene gas.
Before delivery to the store they are gassed with ethylene to trigger uniform ripening. Once the ripening process begins there is no reversing it. The fruit turns yellow and softens and storage is limited to a few days.

Also those bad boys ripen faster when they are laying flat vs hanging. Getting a little hook to hang the bunch of bananas on makes them ripen more slowly

Correct. Fruits ripen through emitting gases. If those gases can be caught (in a box) the ripen process is faster. Also increases ripening of other fruits like apples and so on.

Apples are non-climacteric. Ethylene gas causes degradation of the fruit not ripening. It’s a little technicality.
