Tabletop runway
A tabletop runway is a runway that is located on the top of a plateau or hill with one or both ends adjacent to a steep precipice which drops into a deep gorge.[1][2] This type of runway creates an optical illusion which requires a very precise approach by the pilot.[3]
Juancho E. Yrausquin Airport in Saba, an example of a tabletop runway.
Incidents
- The configuration of Mangalore Airport has been cited as a factor in the Air India Express Flight 812 crash on 22 May 2010. The Boeing 737 Air India Express flight involved overshot the runway threshold touchdown area, failed to stop, went out of control, and rolled down a steep hillside.
- On 27 May 2017, Summit Air Flight 409 stalled on final approach to Tenzing–Hillary Airport, subsequently crashing 122 metres (400 ft) below the threshold of runway 06. The cargo flight descended too low below the threshold altitude, upon which pilots suddenly increased the angle of attack at the low speed. The aircraft stalled as a result of excessive drag and impacted the sloppy terrain 39.6 metres (130 ft) short of the runway.[14]
- On 7 August 2020, an Air India Express Flight 1344 Boeing 737 (as part of Vande Bharat Mission) skidded off the tabletop runway at Calicut International Airport in Kerala with 19 fatalities including the captain and co-pilot.[15]

gollark: ... an x86 assembly typing test link?
gollark: > sqlite is not less complex than this formatYes. *But*, you don't actually have to interact with the SQLite disk format directly because libsqlite3 exists.
gollark: I suspect SQLite would lose out somewhat in storage efficiency, but it could plausibly be faster for many things at runtime.
gollark: It's less complex for everyone interacting with it, since they can just... use SQLite, which has bindings for everything, instead of "zimlib". And by "efficiency" do you mean "space efficiency" or "lookup efficiency"? Because, as I said, SQLite would probably only add a few bytes per directory entry row, which is not a significant increase.
