• Aren’t you an aeronautical engineer?
• Rand Simberg sent the following message at 2:58 PMView Rand’s profileRand Simberg  2:58 PM
• No.
• If you’re interested in aeronautics, I’m the wrong guy. I do space.

• Isn’t spaceflight part of aviation?
• This confuses me a bit lol
• Rand Simberg sent the following message at 3:01 PMView Rand’s profileRand Simberg  3:01 PM
• No.
• Aviation can be part of spaceflight, but isn’t generally. Aviation is about things operating in the atmosphere. For spaceflight, the atmosphere is just an annoyance that you have to get through to get to or from space.

• That’s so cool, my knowledge on the subject is a bit poor, but it’s interesting and I’d love to learn more about spaceflight if you have the time 🙂

• If you’re really interested in space, I’ll connect. I get a lot of invitations from attractive women who I make the mistake of connecting with, who then try to engage in conversation and wanting to make friends with me, and that’s not what LinkedIn is for. But I don’t really have time to tutor individuals on spaceflight. I can recommend reading material.
• LinkedIn Member sent the following message at 3:09 PMView LinkedIn Member’s profileLinkedIn Member  3:09 PM
• Haha, too many women and men like that, and I get a lot of them, but I don’t usually respond. I do have an interest in space, and you can recommend me some reading material, but I’d prefer if you could share some of your experiences with me, it’d be more interesting and rewarding

• I’m sure it would, but I really don’t have time for one-on-one conversations about space to education people. But go read some of my essays: https://www.thenewatlantis.com/authors/rand-simbergRand Simberg — The New Atlantisthenewatlantis.com • 1 min read

• Thank you, I don’t think you need to teach me one-on-one, I’d like to hear you share 40 years of experience in this field when you have the time, I think it would be more interesting and meaningful than reading material

• Again, I’m sure it would be, but I don’t have the time, unless you want to pay me my hourly rate.

I have no idea what a “dog pusher” is. Anyone have any ideas?

But this still seems like a scammer.
