MAYAGUEZ rescue goes better

After reading a book on military rescue ops from WWII onwards today, I was just wondering how the MAYAGUEZ rescue op could've gone a damn sight better in April 1975 instead of the fiasco it was- the biggest improvements cold've been:
-better intel- esp re the location of the ship's crew- not just the P3 Orion, but also covert insertion of US Navy SEALs or Force Recon on Koh Tang to spy the lay of the land (why this wasn't done to facilitate better intel actually beggars belief)
-no chopper crash during rehearsals which killed 23 USAF security policemen initially slated as the ground assault unit OR -the 1/9 Marines, as the experienced Marine outfit uinstead of the green 2/9 Marines, retained as the main ground combat element for the recapture of the MAYAGUEZ & storming of Koh Tang Island
-better communications between the Marines & USN A-7 Corsair, F4 Phantom II fighter-bombers & USAF AC130 Spectre gunships
-better comms with the US destroyers such as USS HAROLD HOLT to enable them to provide fire support to the pinned-down Marines
-earlier deployment of OV-10 Broncos for forward liaison
-the 3-man Marine machinegun team not left behind to be captured, tortured & murdered by the Khmer Rouge- incl poss later covert deployment of Navy SEALs to recover the remains of dead Marines & recover those survivors

WI the MAYAGUEZ episode had indeed gone better for the assaulting US forces ?
