Talk:2452: Aviation Firsts
Someone got into editing just as I thought I'd start, so I'll leave it in case there's population of explanation afoot. But I'm waiting for both uncontrolled powered flight (I don't mean retrothrusted landing procedure) and controlled unpowered flight (ditto, not for parachute descents, at least until they make the subsonic ones full parasails). 184.108.40.206 01:56, 20 April 2021 (UTC)
- Uncontrolled powered flight has caused many plane crashes over the years. Controlled unpowered flight is how every glider, including the Space Shuttles when returning from space, "fly" and land. Nutster (talk) 17:24, 23 September 2022 (UTC)
Is there a well-defined distinction between circumnavigation and orbit? 220.127.116.11 04:13, 20 April 2021 (UTC)
- given that the Wikipedia entry for “circumnavigation” includes a section for orbital circumnavigation, and that there exists a book with the title “Round About the Earth: circumnavigation from Magellan to Orbit” I think that there is not a well-defined distinction. Intuition is that circumnavigations could be split into two disjoint sets, those done at orbital speed, and those done slower, and that would provide a distinction most could agree with, but I found nothing official to support such a bifurcation.18.104.22.168 04:35, 20 April 2021 (UTC)
- I'd instinctively suggest that a true circumnavigation would need to be bookended by touching the surface at the same point (or trivially near - different dock of the same port, hard-landed on a companion runway to that taken off from), or beyond and over its starting track before it finishes (like obviously hard to 'navigate' circumnavigating balloons - and not allowed to be too circumpolar). If a future orbit-inserted Mars-flier eventually 'lands' beyond the point it first started to achieve level flight below Mars's equivalent Karmen-line, having travelled all round the planet in the interim, I might accept that as a special case.
- So far nothing (but Ingenuity) has taken off from Mars, never mind (ditto) landed again, so all the orbiters clearly cannot be counted by this metric, and no rover has driven far enough to have attempted a surface-bound circumnavigation. A long-endurance rover with an advanced version of Ingy for look-ahead might jointly earn the benchmark as first surface and first (punctuated) flown circumnavigations.
- A suborbital semi-ballistic non-stip circumnavigation might be achievable while trying out sample-return technology (though wouldn't be useful, probably only a failure mode of an orbital insertion attempt).
- A surface-launched 'Martian weather balloon' might actually be the first success, though. It might be one designed to touch down, at least daily, for opportunistic sampling, but at the the risk of damage due to dragging/snagging. Or a non-stop trip, until it cannot maintain height/bumps into Olympus Mons. The engineering risks of a free-drifting balloon (capable of Martian flight) are probably being looked at by several teams right now for a future lander payload. 22.214.171.124 12:06, 20 April 2021 (UTC)

In my new favorite sci-fi series, DB Cooper, who got to know the local bigfoot tribe as a kid, and who is called in adulthood Falls-From-Sky, moves to the planet the sasquatch came from to live with the Starfoot and grow garlic with his grandson Charlie. Jerry Boyd's Bob & Nikki series. And their story is a *subplot*.Seebert (talk) 12:57, 20 April 2021 (UTC)
Flight, Landing and Controlled Landing were variously achieved by some or all of the prior landers, depending upon your definition of flight. I would argue that not all landers achieved a controlled landing. I recall a couple that did not do enough aerobraking and ended up doing too much lithobraking instead and were not functional afterwards. Should that all remain in the sentence? Nutster (talk) 02:06, 21 April 2021 (UTC)
- "variously achieved by some or all" means that different landers achieved different subsets. The ones you recall achieved flight (from Earth to Mars) and (crash) landing, but not controlled landing. Barmar (talk) 03:51, 21 April 2021 (UTC)
Hmmm... Reading about how the explanation says "the notion of them [skeletal remains of Amelia Earhart] somehow ending up on the surface of Mars is practically impossible outside the remit of certain conspiracy theories." I immediately had to think on https://what-if.xkcd.com/53/ and https://what-if.xkcd.com/54/ Elektrizikekswerk (talk) 08:33, 21 April 2021 (UTC)
- Thinking about Amelia - her remains were supposedly found, dismissed, and lost. So really, there should be a tick on the Earth side there too Baldrickk (talk) 09:41, 22 April 2021 (UTC)
Adding a table to organize everything might be a good idea because right now the description is a bit confusing. --188.8.131.52 13:21, 21 April 2021 (UTC)
