"The go-around procedure on, e.g., the B747 is - max thrust, flap 20 (jus' like that!) and you don't drop out of the sky but transition instantly to a high energy situation partly by getting rid of drag which has permitted you to keep the engines spooled up just for that eventuality."
Similar with all jet transports. But.....you have the engines spooled up. In this case they were basically without power. Not sure I'd want to touch anything.
