Yes, I do recall PE. Unlike some of the posts, I am not too fond of what PE brought to my life, career and family. As a long time member of the cockpit crew with the original Frontier Airlines (defunct 1986), the arrival of PE on our doorstep was not a pleasant event to those of us who worked for a truly wonderful carrier of forty years. All water long gone under the bridge now but it does not elicit any warm fuzzies in my recollection.
Best wishes.
