Not necessarily. Take a look at the relevant portion of the Lantham Act. It would have to fit one of the provisions therein. It might make a false suggestion of affiliation, but it's arguable.

15 U.S.C. 1125 - False designations of origin, false descriptions, and dilution forbidden

(a) Civil action

(1) Any person who, on or in connection with any goods or services, or any container for goods, uses in commerce any word, term, name, symbol, or device, or any combination thereof, or any false designation of origin, false or misleading description of fact, or false or misleading representation of fact, which

(A) is likely to cause confusion, or to cause mistake, or to deceive as to the affiliation, connection, or association of such person with another person, or as to the origin, sponsorship, or approval of his or her goods, services, or commercial activities by another person, or

(B) in commercial advertising or promotion, misrepresents the nature, characteristics, qualities, or geographic origin of his or her or another person's goods, services, or commercial activities,

shall be liable in a civil action by any person who believes that he or she is or is likely to be damaged by such act.

You violate a trademark if you mis-represent a good or service as that of the trademark holder. And it has to be in the same trademark category that they registered. Having a trademark does not grant ownership of a word, and does not prevent anyone else from using that word. Use of a trademark in reporting and normal discussion is not a violation.

I have the front panel of the VAX 11/780 used to render that scene hanging on my wall, but I got to Pixar after that project. This year and last I've contributed some designs that will fly on a FEMA satellite, and a long time ago did a little work to support the Biosciences mission on the shuttle.

My phone is encrypted and protected with a fairly strong password (12-digit PIN in my case). In addition, the mobile banking app is also protected with a different, fairly strong password. It has multi-factor authentication, but since that is a text to my phone that doesn't count here.

Since my life is on the phone and I use it to constantly stay in touch with family and friends, plus things like navigation, and quick look-ups of information, it is always on me. So much so that I'd sooner forget my wallet or car keys than my phone.

Finally, my phone is not only constantly backed up, it has, essentially, a GPS locator that I can use from my PC to to find it. Just enter "where's my android phone" into Google, assuming you're logged in to your Google account.

I don't need to stand by the rotation theory. However, the 2.5 degrees that the Earth rotates are about equivalent to the downrange distance.

The first stage is going about 1/5 of the target LEO orbital velocity at separation. While you might well model the trajectory as a parabola over flat ground, given the lack of fuel I would expect that SpaceX puts a lot more care into their trajectory. So far I've failed to attract the attention of the person responsible for Flight Club, the most trusted modeling of SpaceX flights, but I'll message him directly.

Well, Alastair, you should probably not get snotty and ad-hominem, unless you want me to comment on how a one-time sci-fi author and the Unix guy at Dish doesn't really have more authority than the random person one might find in the SpaceX group on Reddit.

It happens there are a few people over there who are rocketry professionals, have the math, and have followed SpaceX long enough. So, sure, their opinion can indeed be trusted.

So far, we have a suggestion from one of the lesser folks there that raising the apogee takes advantage of the Earth's rotation. We'll see if we get the attention of the right people.

It seems to be a common misconception that orbital mechanics somehow knows when you are in orbit and does not work otherwise. But that is as silly as saying that relativity only works near light speed. These things always work regardless of speed, it's just that their effects are macroscopic at greater speeds.

Here's an illustration of the boost-back to RTLS trajectory. You can see that it very definitely goes up. And to prove from observation, you can actually see where the two trajectories separate in photos from yesterday's launch. It's a rather dim curl up, and another continuing East, in Jason Ruck's photo and John Kraus's photo.

At the speed of stage separation, they rocket isn't going fast enough to stay in orbit, but it is definitely in the regime where orbital mechanics has a macroscopic effect. If you think about it, this is going to be the case at some reasonable fraction of orbital velocity.
