From my pilot friend who has been watching. Says that the 5 known air fuelers just went dark over the DC/ Deleware/ New Jersey area as well as a E6B which is a C&C aircraft. There were no airports near them at the time so they turned their transponders off. Something may be happening.

• 1 fueler appears to have come back live and is flying patterns at a lower altitude of 3k feet, but the rest are still missing.
