					<description><![CDATA[M. Murcek,

Most of the people who hate Musk and wish him gone do so because they are self-involved lefties with defective mental processes high on baseless anger, envy and resentment.  Don&#039;t hold your breath waiting for them to actually &lt;i&gt;think&lt;/i&gt; about much of anything - it hurts their widdle noggins.

Jeff Wright,

The replacement of Viasat by Starlink on United&#039;s 1000-plus-plane fleet will be a process rather than an event, but, yes, the process has now started.  That was a big win for SpaceX.  I suspect more will be coming, and mostly at Viasat&#039;s expense.

Peter Francis,

Your surmise is correct, it&#039;s a matter of payload mass and/or orbital destination.  The Starlink missions go to low orbits, but they&#039;re also packing absolutely maximum load-outs so they need the drone ships to catch the boosters and the 2nd stages need the full-sized MVac engine bell.  Missions with much lighter loads also need drone ship booster landings if they are going to sufficiently high orbits or are bound for deep space.  A few fairly rare such missions even require a completely expendable Falcon 9 launch.  Lighter payloads going to relatively low orbits can be launched with enough propellant in reserve to allow a return-to-launch-site (RTLS) landing on one of the LZs.  Some such missions can even use the &quot;shorty&quot; Mvac engine bell which gives up a bit of performance in return for requiring only about 1/3 as much expensive alloy to fabricate.]]></description>

					<description><![CDATA[I have much wondered why some Falcon 9 first stages land back at launch landing pads while others land on drone ships. Is this because of launch trajectory, payload mass or all of the above? Asking because &#039;where&#039; affects costs of refurbishment of first stages for next mission(s).]]></description>
