Plot hole: After they shoot the glass and McClane escapes, the terrorists all just leave. There are limited ways out of the room, there must be a blood trail over the glass, he's moving slowly...and they let him go.
Suggested correction: Hans has no interest in John anymore; all he wanted was the detonators. It's not a plot hole, just a non-meta character decision. Sure, if they'd persuaded John, things would have worked out differently, but that's only obvious in retrospect.
Corrected entry: A waiter offers John champagne but instead gives him what looks like red wine.
Correction: There's no mistake here. The waiter has a range of drinks on his tray. He asks if John would like Champagne, but John chooses red wine instead.
