I apologise for my very sloppy post. I presumed what I saw was the 707 variety (refueling a Hornet). It certainly had four engines. May have been a KC-135. There were joint exercises on at the time so it may not have been a RAAF aircraft. Incidentally, my cousin's son was Squadron Leader on the tankers (now flying for QANTAS) and it was my cousin who referred to him as flying the 707 tankers so I just "assumed"!
I meant the C-17 heavy lifter. They are amazing. Very, very quiet. They fly very low (probably about 300ft) and you can clearly see the pilots if you hear them in time and they come over the top of you. But you never really hear them unless they are right on top, so I usually only see them by accident.
Mount Bodumba is on the property next door. It is a bit over 600m. The Blackhawks do some night training (probably with SAS) on it sometimes. The Hornets are mostly high up. Lately they seem to have been in pairs practising missile drills - one drops about six magnesium flares and a second one dives down through the pattern on the tail of the first. Occasionally they come over lower, even at tree top height flying the creek (it often seems to happen just before they do the Riverfire thing up the Brisbane River). I saw one do a missile line up on the house just down the road one day - diving down at a fairly shallow angle and pulling up about 200m out. It would have rattled the windows!
