This movie was filmed during the last day of operation of PBA (Provincetown Boston Airlines) which at that time was acquired by some major airline companies as depicted by the many different paint schemes on the airplanes. Although they may have tried to fragment the company, they never fractured the spirit of the employees right up to the last day and beyond. Oh! Where Have You Gone OMV?
This is a 30+ year old SD video.
