I'd have to disagree. The way I associate these words causes me to think of something "revolutionary" when I hear "boom". i.e., it's shaking up the market. Contrary to that, "glide" and "zip" (I know these are just examples) sound more soothing and definitely not attention-grabbing. If the aim of the company were to provide luxurious flight, then maybe that would be fitting. But as I see it, the company really does mean to shake things up, in which case their name is already fitting.
Obviously, everyone has their own opinions, but I thought sharing an opposing perspective would be useful in showing that it's definitely not a one-sided topic.
I too have found that grumpiness and negativity are so toxic, counterproductive, and worse than useless that they are up there in terms of dealbreakers.
1. "boom" is not the right name. Explosions. Annoying/scary sonic boom. These are not the associations you're looking for. Try "glide," "zip"—something along those lines.
2. In your very first team picture I see a grumpy-looking fellow with hands in pockets. A few images on he's still there, now joined by another grump with crossed arms. These people look disengaged and/or disgruntled. Call me shallow, but it just doesn't look right for a team supposedly revolutionizing aviation. Ask your team to look engaged when taking PR photos. Or if there's a deeper attitude/team dynamics issue there, man fix it now. I don't want my life "booming" into oblivion because some guy was fed up.
