Clearly flight 175 had two Pratt and Whitney JT9D-7R4D engines.
Take note of the engine type especially the cooling duct assembly is used on it. the murray street engine is NOT a JT9D-7R4D engine.
The name of the component in question is the HPT Stage1 Cooling Duct Assembly. This component was part of the early JT9D-7 series engines that were used in development of Boeing's 747 line of aircraft. The "7" series engines have gone through many revisions but are exclusively used on 747's. Many years later, P&W decided to work with NASA in the development in a new technology to improve engine performance and reliability. This improvement was made specifically to this section of engine. Tangential On-Board Injection (TOBI or "R" for Radial) was the newest improvement to reduce nozzle temperatures by over 2% which could open the door for a more powerful engines based on the "7" series engine. The new model of engine would be called 7R4+Revision Letter. The 7R4D engine is the one that is specified for United Airlines Boeing 767's.
The engine found at Church and Murray didn't seem to be a 7R4D.....it seemed to be a 7J. The only way to confirm this is to search for the engine and take a look at the diffuser casing to verify a match.
There are two data points indicating that the Murray Street engine is a Pratt and Whitney JT9D-7 series engine: the HPT Stage 1 Cooling Duct Assembly which the manufacturer indicates is for use ONLY with the 7 series engine, and we have the diffuser casing of the Murray Street engine matching perfectly the diffuser casing of a 747 engine --the model of Boeing aircraft that the JT9D-7 series engine was exclusively used."
All data so far seem to indicate that the Murray Street engine is not a JT9D-7R4D engine, as would have been on Flight 175.
American Airlines Flight 11 struck the North Tower. Its tail number was N334AA. It was a Boeing 767-222ER. Flight 11 had two General Electric CF6-80A2 engines. the Murray Street engine certainly is not a GE CF6 engine from Flight 11
So how did a 7-series 747 engine wind up on Murray Street?
One of the most viewed biggest diesel locomotive videos on youtube! Union Pacific 6915 on public display in Pomona, CA. This big diesel is one of a few surviving examples. The new EMD SD59MX I caught in Redding, CA on my return trip home.

An update on the building of a low temperature differential Stirling engine capable of producing 1 to 2 Watts from heat sources with a 100 Deg C temperature difference. Note: I'm transferring videos from YouTube to BitChute. This one is nearly two years old. I still intend to complete it, but have had a lot of things on my plate. I appreciate your patience.
I've often wondered if one could make power using a low temperature difference (LTD) Stirling engine. Some initial calculations are presented here; including anticipated efficiency and amount of heat transfer required. I'm defining "LTD" as the difference between the freezing point of water to the boiling point. In the end, I'm looking to produce between one and two watts of electrical power. This project is likely a fool's errand, but if it is I want to show why.
A simplified design procedure based on a paper is used to calculate the required volumes for the displacer and the power piston. A 3-D model was made of the proposed engine design using primarily wood construction.
How dare they call them Search Engines, when they can't find what you are looking for, but instead try to direct you every where else. It came about when I realized how Blogger, a service of Google, did not follow my settings but instead their own. I did a Search Engine test using the name of my Blog, as it appeared on the Browser Tab: Our World is Awakening Visit my NEW Blog: http://ourworldisawakening.net
