New JoNES article to shoot down: Transponder Activity

After two years in hibernation, Kevin Ryan's "Journal of 9/11 Studies" has published a new article:

"Implications of September 11 Flight Transponder Activity" by Aidan Monaghan, May 2017.

Abstract:

Originally Posted by Aidan Monaghan It has been the consensus of informed observers that the loss or alteration of Secondary Surveillance Radar (SSR) information for the four September 11 flights was caused by accused hijackers allegedly seizing control of the aircraft flight decks and manually turning off or adjusting each plane’s Mode S (Mode Select) transponder. This was presumably for the purpose of evading detection and interception by U.S. air defense systems. However, this view appears to be based only on circumstantial information - the simple loss or change of SSR flight data to Air Traffic Control (ATC) – and seems unsupported by conclusive facts. Following these transponder operation changes, ATC was still able to tag and track the primary radar returns of three flights and estimate their locations, directions, ground speeds, and even altitude changes.

I haven't read it, but since Monaghan is a Truther, Ryan is a Truther, and the JoNES is a Truther magazine, and since a 9/11 Truther, by my definition, is a person who is systematically wrong about almost every 9/11-related issue they utter an opinion on, I strongly expect it to be stupid crap. So have at it, beachy, Reheat, and anyone else interested in the air traffic issues.

EDIT: Nevermind. No edit.
