Tomahawk Missiles over Syria

Trump had 59 Tomahawk missile fired into Syria at an airfield because Syria used chemical weapons on it's own people. The damage was reported as heavy. But videos showed little damage; runway was in use the next day; aircraft revetments appeared untouched; no damaged/destroyed aircraft seen--only one aircraft seen and it was in an undamaged revetment; no bomb craters were seen. So just what was the damage? Understandably only the one aircraft was seen because Trump had alerted Russia to the attack and they (most likely) alerted Syria so Syria's aircraft could be relocated away from the intended airfield. Remember when Trump said he'd never disclosed any military action he might take?
