Either way all we know is the sprinklers seemly did not work on 9/11.

Exactly so sir, this is what i was trying to portray with
North, North-East, North-West
As a possible approach. Naysayers still ignoring the Z-axis by focusing only at X and Y.

Deluge systems are used in places that are considered high hazard areas such as power plants, aircraft hangars and chemical storage or processing facilities. Deluge systems are needed where high velocity suppression is necessary to prevent fire spread.
Deluge Fire Sprinkler Systems differ from conventional Fire Sprinkler Systems in the sense that all nozzles employed in the system are open and when water is released into the system it flows from all discharge devices. As such, this special type of system is generally found within industrial type hazards that require the application of water over a large hazard or area.
Sprinkler System Types
Wet pipe systems. Wet pipe sprinkler systems are the most common type of fire sprinkler systems. They’re reliable because they are simple, composed of only automatic sprinklers and, usually, an automatic alarm check valve. An automatic water supply provides water under pressure to the system piping. All of the piping is filled with water. And, when the automatic sprinkler is exposed to sufficient heat, the heat-sensitive element (glass bulb or fusible link) releases, allowing water to flow from that sprinkler.

And how fast might have AA11 or UA175, flown with control descent(observe time and altitude delta)
When completed in 1973, the South Tower became the second tallest building in the world at 1,362 feet (415 m). Its rooftop observation deck was 1,362 ft (415 m) high and its indoor observation deck was 1,310 ft (400 m) high.[97] Each tower stood over 1,350 feet (410 m) high, and occupied about 1 acre (4,000 m2) of the total 16 acres (65,000 m2) of the site's land. During a press conference in 1973, Yamasaki was asked, "Why two 110-story buildings? Why not one 220-story building?" His tongue-in-cheek response was: "I didn't want to lose the human scale."[99]

Not much time to line up approach, especially if have buildings in way
Only possible approach was north, even then gave some buildings partially blocking that avenue of approach
But the conspiracy fools are constantly chirping about how the hijackers were such lousy pilots
Cant have it both ways …………..
As I pointed out already we learn from NIST the fire alarms were disconnected somehow on 9/11!
