Not seen on ADSB at the moment.
Roger. AF1 not seen.
USAF Boeing C32A with callsign SAM740 heading for DC also; rendezvous with POTUS when AF1 arrives there from NJ?
Not sure who is in that plane but the SAMxxx callsigns tend to be officials.
The flight didn't start in Indiana but that's where the ADSB radar trace first ID'd it.
R7, over.
