Yes I know it's Hal so I take it with some salt till I see it again. Within the hour, every single military aircraft of the Israeli Air Force went "dark." EVERY aircraft transponder was turned off. As of 4:40 PM eastern US time on Tuesday afternoon, NOT ONE Israeli military aircraft is signaling via the typical, normal, civilian, transponder system. This is unusual. Earlier today, everything was typical; there was even a "busy" deployment of Signals Intelligence aircraft as shown on the radar display below https://halturnerradioshow.com/index.php/en/news-page/world/israeli-military-goes-completely-dark
