I met Dave on the Boeing program known as Connexion-by-Boeing, and we worked on the same test team, including TDY in Japan. Dave's technical expertise and contributions were indispensable; his can-do attitude and cheerful countenance were simultaneously encouraging and uplifting, and they never failed. Dave was an asset to The Boeing Co. and a credit to his family. I will always remember Dave Guichard with collegial affection (Note: I retired Boeing in 2006.).
