Dan,
This is a momentous occasion, to be sure, but I offer a word of caution.
Please use discretion when inviting a crowd to an EAB's first flight. It's a human factors pitfall: It can distract the test pilot and crew, placing unnecessary pressure on the test pilot to 'get her in the air' on a first flight. If the airplane's not good to go, he/she should NOT get her in the air. It's a test flight, not a christening. A smaller group presents a smaller distraction from the day's mission.
In addition:
- If the airplane doesn't fly for whatever reason, a smaller crowd lessens the level of possible embarrassment among the builders.
- If the airplane launches and something goes wrong (God forbid), you will have pre-positioned quite the emotional group of witnesses.
I'm sure this isn't your first rodeo. Just please be careful. I wish y'all a successful first flight!
****UPDATE****
Mel Asbury has set me straight: The first flight for the public will NOT be the actual first flight (I breath easier). Dan, I wish you the very best for a great event! If Walt gets finished with my panel upgrade in time, I'll fly down and join the festivities.
