oh you funny guys...its a trick question...everyone knows a METEORITE is a meteor that has struck the earth.
now, the trick is prior to being a meteorite, it was a meteor, and I'm assuming a GLOSTER METEOR properly equipped IAW ICAO regulations with an operating 4096 mode c transponder
so, yes the tCAS will pick up the gloster meteor, but after it crashes into the earth, it won't.
oh you british...!
