The reason I ask is because these sounds were first heard in an English release in the '93 laserdisc remix, I believe; if I remember correctly they are not present on even the mono mix. Yet the '93 and the SE mixes contain these sounds, and from Belbecus' article about the construction of the '93 it says the Ben Burtt added various extra sounds to the 70mm that he had used for the foreign language mixes. I wonder why he didn't put most of the mono sounds, like the Falcon's gun beeps and 3po's tractor beam line. Hmm.
I ask about the breaking glass in particular because it's one of the most noticeable differences between the '93 and every prior English mix--if it's there it means he didn't come up with it as a new sound in '93, as I'd thought, but instead in late '77.
