Alan was a wonderful person and an even better friend to me. He made me laugh even when I really didn't want to! We enjoyed many times together while he lived here in New Orleans. He cared about everyone and was always willing to help in whatever way he could. We joked about many things and often spoke of life and how every day is precious. I will miss my friend and our conversations. I'm sure we will meet again ! Keep swinging from the left side of the plate Alan !

We are so sorry for the Loss of Alan... to his family, friends, and anyone who he has befriended and touched over the years. For me, he was a Brother from another Mother. Alan was a good friend to me and my family as well as a business partner and life co-conspirator (in fun things). I always introduced my friends and associates to Alan as a "Rocket Scientist" and one of the smartest business people I have known. And, like me, he loved his toys. Where else could you go and work on a business plan in a high-rise apartment and then take a break to shoot pellet guns against a steel plate we hung on the back of his front door! :-). Or, have a squadron of flying helicopters and drones doing battle in the living room. Alan and I were not only friends and partners, but also traded roles as Mentors to each other in business and life issues. When Alan showed up to my son's Bar Mitzvah, or would take their teenager "drama" calls, he made an even bigger impression on my kids. He was a sound-board for my high school son and college-aged daughter who both spoke to him within the past few months. He was always available and took to others, both young and old. He was one of the most devoted sons as well. I met him at a time where he was struggling with being a good son and caretaker to his mother before her passing, while she struggled to stay in her home. I am so glad I was able to see Alan last August when we detoured from New Jersey to San Francisco through Los Angeles. Alan and I hit the Deli in Marina Del Rey as usual and talked and laughed and solved the world's business and technical problems for 3+ hours. And he looked great and was full of energy, but you could tell the previous year had taken a toll on him. Cyndie, you were an amazing angel for him and he was truly happy and lucky to be with you. To Mark and your family, Alexa, Harold and Anita, Jules and other family members that I have met or those I have not met, I know he loved you all, no matter what the circumstances or distance. He was an extremely generous man, with strong convictions, sense of duty and full of purpose. He tried to shield everyone from harm, yet would rarely, if ever, admit he was in trouble or needed help. We will remember him always and he will be missed by the many people he touched in his personal, business, military, Jewish, family, political, and scientific worlds in which he actively participated. Alan, as a pilot and space dreamer, fly high. Love you Alan. From David, Lynn, Maxine and Stephan Rosen.

It's hard to believe that Alan has passed away. Mom & I just viewed the service and the words of Kyle, Alexa and Mark were beautiful. Mark really summed up how I thought of Alan, a real charmer. In my teens and early college days, I had a crush on his good looks and hair, and was sad he was my cousin and not just an available man. My girl friends felt the same. He was an excellent host when my friend, Marcy, and I spent a few days with him in San Francisco. He gave us the royal tour and introduced us to the wine country. He even told us that if we picked up any men, to leave one of his ties on the door knob and he would find somewhere else to stay. Alan will always be in my heart with fond memories.

It is difficult for me to believe that Alan is no longer with us. I spoke with him 3 weeks ago and he asked me to plan a trip for the two of us to visit our cousins in Argentina. Unfortunately, this will never come to pass. Alan was always a pleasure to be with and we had many great times together when he visited Chicago. Being with Aunt Sophie, Uncle Joe, Alan and Mark was always very special to me and Sonny. Alan will be in my heart forever. Love you cuz....

To Cyndie and Alan's family, I am truly at a loss for words. His unexpected death has taken us all by surprise. Alan was a very caring and generous person and I am so glad that I had the opportunity to meet him. May the good times that you all shared with him be remembered and be a comfort to you all at this time and in the future. my condolences to all. Fondly, Pamela

We are so sorry to hear that our cousin Alan has passed away. We're never ready to say goodbye to family, and it's particularly difficult since Alan's passing was so sudden and unexpected. He was the handsome, dashing and exciting cousin, always ready with a great conversation, and a wonderful smile. Alan's parents, Uncle Joe and Aunt Sophie, were our "second parents", and even though they left Chicago in 1953 to raise their family in L.A., the Greenstadt and Kosova families have kept close ties ever since. It's hard to believe that Alan is gone, but he will never be forgotten.

Death is sad. We are all dependent on our memories of a close person's life to console oneself. Alan's parents were my aunt and uncle and were as close as a second set of parents in my youth. I have clear memories of Alan's birth, of playing with him in his crib and of his early childhood. Alan was a man who was gifted with great intellect and wonderful social graces. His life was not always as joyful as he and those who cared for him might have enjoyed but through all that came and went he remained full of optimism and caring. I last spoke with him 2 weeks ago after a hiatus of several months. As usual he was full of optimism and excitement about his new business venture. Life is fleeting and unpredictable. Enjoy it. The future is always better than the past-until it ends. Len Kosova

I am so saddened to hear that cousin Alan passed away. I had lunch with Alan just a few months ago. He looked good, seemed well and happy, and was upbeat about the things he was doing. We talked about family memories and it was clear that family meant a lot to him. My condolences to both family and friends - Alan will surely be missed. Edie Levenson

Sorry to be late joining here. Hard to believe it's been 3 1/2 years. Alan and I came together at Optical sometime in the first half of 1975. He was my boss, and we came brothers very quickly. We learned to fly together, ski together, and run that little business together. In that time, there were only two companies in the subscription movie business on cable. Pay-TV it was called. The other guys were beaming the movies to the cable operators via satellite. We leased a channel from the cable operator, set up an origination studio, and fed the movies directly to our subscribers' homes. We marketed and billed our customers directly. The other guys beamed the movies to the cable operator, who did the marketing and billing - and made more money, so that when our lease contracts ended, the cable operator bought our customer bases and signed up with those other guys - HBO. Then Alan's and my focus switched to ultralight aircraft. Pioneer Systems, Optical's parent and the country's leading parachute supplier to the military, bought a small hang-glider business in Salinas CA. We (Alan now as Pioneer's president) developed the FlightStar, the revolutionary next-gen machine that conventional general aviation dealers fell in love with. We lost an internal political battle about the time that the industry's safety record set off alarms that doomed the nascent business - and the FlightStar. ... We were planning to get together in the batting cage. That'll have to wait for softball in heaven. See you then, my most special friend.
