Re : 'Stealth & UFO'
Daventry Sector - Yesterday. FL240 (level capped)
TCAS target left wingtip - 1nm, solid diamond, indicating '00'
Followed us for about 10mins. altered Heading & Level with us.
Suddenly disappeared, no warnings !!
Is this a 'ghost' generated by TCAS ? if so how ?
Capt. PB care to comment ?
