Destroyed the Phantom at the Covenant camp in Reunion on Heroic difficulty.
At the Covenant camp in Reunion a Phantom dropship lingers - destroy it, on Heroic. Grab a power weapon (Fuel Rod, Rockets, or a turret) or commandeer a Banshee/Wraith and focus it down before it flies off. If it escapes, revert to the last checkpoint and try again.
