Narrative:

ZDC handed off small aircraft X, C208, supposed to land cbe (cumberland, md). The aircraft was on a 140 degree heading passing cbe and the center could not raise the aircraft. Xmissions were made over vors, 121.5, and ZDC, iad, dca frequency to no avail. I worked a MO21 out of hef as X was now 50 mi southeast of cbe, and tried to vector the MO21 to get a visual on aircraft. X outran the MO21 and no close-up view could be attained. Eventually, a BE90 out of nyg was launched and it intercepted the aircraft approximately 120 mi southeast of cbe. Evidently the BE90, in close proximity to X, wakened the sleeping pilot and very quickly thereafter, the pilot of X contacted ATC. I ended up working the aircraft on the way back to cbe, asked if X was fuel critical and the pilot replied curtly, 'negative.' landed without incident at cbe. I'd say that military Y, BE90, saved that pilot's life!

Original NASA ASRS Text

Title: PLT OF X FELL ASLEEP AND OVERFLEW DEST. MIL Y INTERCEPTED X AND WOKE PLT UP.

Narrative: ZDC HANDED OFF SMA X, C208, SUPPOSED TO LAND CBE (CUMBERLAND, MD). THE ACFT WAS ON A 140 DEG HDG PASSING CBE AND THE CTR COULD NOT RAISE THE ACFT. XMISSIONS WERE MADE OVER VORS, 121.5, AND ZDC, IAD, DCA FREQ TO NO AVAIL. I WORKED A MO21 OUT OF HEF AS X WAS NOW 50 MI SE OF CBE, AND TRIED TO VECTOR THE MO21 TO GET A VISUAL ON ACFT. X OUTRAN THE MO21 AND NO CLOSE-UP VIEW COULD BE ATTAINED. EVENTUALLY, A BE90 OUT OF NYG WAS LAUNCHED AND IT INTERCEPTED THE ACFT APPROX 120 MI SE OF CBE. EVIDENTLY THE BE90, IN CLOSE PROX TO X, WAKENED THE SLEEPING PLT AND VERY QUICKLY THEREAFTER, THE PLT OF X CONTACTED ATC. I ENDED UP WORKING THE ACFT ON THE WAY BACK TO CBE, ASKED IF X WAS FUEL CRITICAL AND THE PLT REPLIED CURTLY, 'NEGATIVE.' LANDED WITHOUT INCIDENT AT CBE. I'D SAY THAT MIL Y, BE90, SAVED THAT PLT'S LIFE!
