But at least for most likely targets, we'll use the G-8 for short

invisible to the military folks and lack of transponder alone would
probably bring out the fighters.

The last plot on the military radar's tracking suggested the plane was
flying toward India's Andaman Islands, a chain of isles between the
Andaman Sea and the Bay of Bengal, they said.

The last sighting of the aircraft on civilian radar screens came shortly
before 1:30 a.m. Malaysian time last Saturday (1730 GMT Friday), less
than an hour after it took off from Kuala Lumpur, as the plane flew
northeast across the mouth of the Gulf of Thailand. That put the plane
on Malaysia's east coast.

Malaysia's air force chief said on Wednesday an aircraft that could have
been the missing plane was plotted on military radar at 2:15 a.m., 200
miles northwest of Penang Island off Malaysia's west coast. This
position marks the limit of Malaysia's military radar in that part of
the country, a fourth source familiar with the investigation told
Reuters.

When asked about the range of military radar at a news conference on
Thursday, Malaysian Transport Minister Hishammuddin Hussein said it was
"a sensitive issue" that he was not going to reveal.

They also gave new details on the direction in which the unidentified
aircraft was heading - following aviation corridors identified on maps
used by pilots as N571 and P628. These routes are taken by commercial
planes flying from Southeast Asia to the Middle East or Europe and can
be found in public documents issued by regional aviation authorities.

In a far more detailed description of the military radar plotting than
has been publicly revealed, the first two sources said the last
confirmed position of MH370 was at 35,000 feet about 90 miles off the
east coast of Malaysia, heading towards Vietnam, near a navigational
waypoint called "Igari". The time was 1:21 a.m..

The military track suggests it then turned sharply westwards, heading
towards a waypoint called "Vampi", northeast of Indonesia's Aceh
province and a navigational point used for planes following route N571
to the Middle East. From there, the plot indicates the plane flew
towards a waypoint called "Gival", south of the Thai island of Phuket,
and was last plotted heading northwest towards another waypoint called
"Igrex", on route P628 that would take it over the Andaman Islands and
which carriers use to fly towards Europe.

Since the Malaysian military is admiting to seeing "something" on their
radar, it's not clear if they've been asked (or stated) if they
scrambled jets to intercept / investigate.

How many times during the last month, the last year, the last decade has
the military in those countries scrambled jets to investigate unknown
radar contacts?

Like any human system, if it's not excercised or utilized regularly
there's no garantee it will operate according to plan at any given time.
