United Technologies advertised a used Beechcraft Baron airplane for sale in an aviation journal. Attorney Thompson Comerford spoke with a United agent who described the plane as "excellently maintained" and said it had been operated "under $135$ flight regulations," meaning the plane had been subject to airworthiness inspections every $100$ hours. Comerford arrived at a Dallas airport to pick up the plane, where he paid $$80,000$ for it$.$ He signed a sales agreement stating that the plane was sold $"$as is$"$ and that there were $"$no representations or warranties, express or implied, including the condition of the aircraft, its merchantability, or its fitness for any particular purpose." Comerford attempted to fly the plane home but immediately experienced problems with its brakes, steering, ability to climb, and performance while cruising. $($Otherwise$,$ it was fine.$)$ He sued, claiming breach of express and implied warranties. Did United Technologies breach express or implied warranties? Why or why not?
