A Citation Jet landed Runway 33 I told him to turn right on Runway 24 right on 'C' contact Ground point 7. I then told Ground to cross Runway 33 at C3. I then cleared a Saratoga for take off on Runway 33. Ground already gave the Citation the crossing; so when he saw the Saratoga taking off he asked Ground to confirm he can cross Runway 33; at the time he was holding short off Runway 33 on C3. The overhead air conditioner was loud at the time and Ground and my Instructor did not hear me give the clearance. Also if we can make intra-facility coordination on recorded line it would help that way we can confirm the crossings.
A Citation Jet landed Runway 33 and was told by my Trainee to turn right on Runway 24 and right on 'C' and contact Ground on point 7. Apparently my Trainee told Ground they could cross the Citation at 33/C3 which I didn't hear due to the extremely loud overhead air condition unit we have in the Tower Cab because the smaller one doesn't cool the Cab down on hot days. My Trainee then cleared a Saratoga for take off from Runway 33. The pilot for the Citation called back and asked Ground Control if he was cleared to cross because he saw the Saratoga on take off roll from Runway 33. The Citation from my observation did not cross the hold short lines of Runway 33 at 'C3'. I recommend that a line for intra-facility coordination be installed on the ETVS so that it brings more awareness to the crossings and holds people liable and prevents the 'he said; she said' that can happen in a situation like this.
PNE Controller in training described a crossing runway conflict event when coordination between Local and Ground was confused and/or incomplete; the reporter listing a loud air conditioner noise as a contributing factor.
