Find correct name The airport is not listed as João Paulo II anywhere. The airport's own website calls itself simply Ponta Delgada, and has no mention of João Paulo.

Review

Category:History of Portugal: lots to remove there
Template:Regions of Portugal: statistical (NUTS3) subregions and intercommunal entities are confused; they are not the same in all regions, and should be sublisted separately in each region: intermunicipal entities are sometimes larger and split by subregions (e.g. the Metropolitan Area of Lisbon has two subregions), some intercommunal entities are containing only parts of subregions. All subregions should be listed explicitly and not assume they are only intermunicipal entities (which accessorily are not statistic subdivisions but real administrative entities, so they should be listed below, probably using a smaller font: we can safely eliminate the subgrouping by type of intermunicipal entity from this box).

There seems to be something wrong here. Bartolomeu de Gusmão did fly a passarola 1 km over Lisbon. This is well documented. —Preceding unsigned comment added by 62.169.67.134 (talk) 03:03, 25 March 2009 (UTC)[reply]

What's a passarolla?

I've noticed that according to this article, Gusmao's passarolla is described as an aircraft powered by magnets and/or by air blown through its sail by means of bellows. This is implausible, since neither method can create sufficient lift to make the passarolla airborne. In addition, according to other accounts, the passarolla may have been a type of glider, or it may have been a hot-air balloon (in which case the "aircraft" on the picture would actually be only the balloon's gondola). I would like to see this question resolved, because the methods of lift and propulsion described in the article simply would not work.

Name and nationality

Two books I have on the history of flight (Angelucci & Matricardi, and Wragg) both refer to him as Laurenço de Gusmao and describe him as Brazilian. My books are written in English while the references in the article are in, presumably, Portuguese, and this is of course the English Wikipedia. Are there more authoritative references for the current title of this article in English, Bartolomeu de Gusmão, and the nationality currently given as Portuguese, or can I move and update the article accordingly? — Cheers, Steelpillow (Talk) 21:40, 21 June 2014 (UTC)[reply]

Yeah, these issues of disputed nationality tend to blow up into big edit wars, which I'm not interested in participating in, but here's my two cents on the issue: Can't he be both? He's from Brazil, so he's Brazilian, and he's a citizen of Portugal, so he's Portuguese. After all, a native of Okinawa is both Okinawan and Japanese.

This article needs a major improvement, if not rewriting

At the very end it should be proven with quotes that:

> Bartolomeu Lourenço de Gusmão (c. 1685 – November 18, 1724) was a Portuguese priest and naturalist from the Colony of Brazil, noted for his early work on lighter-than-air airship design

I'm sorry but it is completely unclear that "Passarola" was a lighter than air airship. It was already mentioned on the talk page, neither description nor its original image mention any way to provide it lighter than air lift i.e. no balloon or anything. It is quite possible that "Passarola" was a project of a heavy than air glider/plane.

The only mention that he made a balloon comes from a source which was written more than 60 years after his death and after the flights of brothers Montgolfier, as an attempt to claim that a Portuguese was the first balloon inventor.

> The vessel was to be propelled by the agency of magnets which were to be encased in two hollow metal balls.

This mention of its supposed magnet engine certainly needs an explicit description and quoting.

> Developing the ideas of Francesco Lana de Terzi

Francesco Lana had a project of a vacuum airship and it is pretty clear how his flying boat was supposed to fly. If "Passarola" had vacuum metal balls like Francesco Lana's airship, it would be obvious that de Gusmao used Lana's idea, but those two rather tiny balls on the illustration were apparently supposed to contain some magnets... 77.35.251.90 (talk) 13:55, 7 September 2016 (UTC)[reply]

a notice

according to R. Sarrou "....on 5 August, Gusmao put his airship to fly in front of the king and his court at a height of 20 spans, but the airship caught fire and had to go down and the fire was difficult to extinguish. On October 30, was done a second attempt with success this time. The airship went up very high and went down intact. The invention caused excitement, it was called passarola or flying gondola and Gusmao was appointed king heleonomus and became academic, while he was given the nickname "flying". Afterwards a sudden silence covered everything." — Preceding unsigned comment added by 85.72.101.175 (talk) 01:34, 29 November 2019 (UTC)[reply]
