It's all that combined with lots of immaturity. Both Yeager and Hoover are ledgends and both are show boaters. Why not? They paid their dues! Both have contributed a great deal to general aviation and to the country and deserve the utmost respect. They are also big big buddy's since their early days as newly graduated cadets. To say that Yeager needed a Piper demo pilot to assist him is just total immaturity along with the other negative comments from the peanut gallery.
