which can't be said of your post. Tapes have 30 mins each, can you state the aprox times of the occurrence you refer?
So sorry....
Listen to the BOS Tower tape for 3rd Dec 0000-0030z at about 0:45mins to 1:00 and then BOS Departure Dec 0000-0030z 3:00
And to avoid any other mystery the voice is a very well spoken lady.
After listening to 5 hours of BOS I wanted to hear them finally depart.
