Gulfstream IV in Bedford MA

[VFD]

If they HAD started and taxied with the Gust Lock inadvertently engaged (contrary to the checklist) and then only noticed it that had been accidentally left on and so then released it while hydraulic power was on the flight controls (again contrary to the AFM) is there any chance that the Gust Lock throttle pin could/would release and not the mechanism that locks the flight contols?

This is where I was early on.
Could applying hydraulic pressure to the flight controls with the Gust Lock engaged applied enough pressure to the elevator that the latch would not release. Then along with the impacts of the accident along inadvertent control inputs from the accident along with loss of hydraulic pressure cause the latch disengage?
