Not on a fire like this, no. That amount of water all at once would just finish destroying the structure. It also wouldn't be terribly effective, since it can only hit fire that exposed to the sky (which isn't the fire that actually matters... if the fire is visible from above, it has already burned though whatever it is you're trying to save).

Aerial operation would also require evacuating the area completely, which would end all other firefighting operations (so you'd actually be reducing the overall firefighting capacity on scene).
