Since other sightings are unconfirmed & hazy, the only other reasonable info to go on is the Radar info, otherwise every one is looking for a needle in a hay stack. From original reports(read all earlier blogs) the Location of 1st Radar Ident E151 18' S32 03'. MDX got to this loc because it was 6 degree's off course from Taree, went west through ice cloud & lost it's position to turn left. After Ident MDX turned around & headed roughly 95 to 100 degree's magnetic to get to the coast so to be at a lower altitude to get the ice off & to regain orientation, but MDX went back through the ice cloud & collected more ice than the aircraft could handle & came down. From the Flight Plan & having a 30 to 40kt tail wind the ground speed matches the time it would take to go that distance from 1st radar to when MDX disappeared over Craven/Stratford. From the Pilot calling out his Altitude & the timing in the recording, I worked out MDX descending at 1600ft/min, from Craven/Stratford crash area is about 9km/5nm to the east. There are a few variables, was MDX actually at 5000ft over Craven/Stanford or bit higher or lower? The Radar said over Craven, but could have been over Stanford if going direct to Foster(lights) or in between? Was MDX in a high speed descent or a stalling lower speed descent?

Martins email

Hi Nev,
I had never heard of VH-MDX until 2 weeks ago. The 4wd club I am involved with are being asked to contribute ground support during the planned search this October. I am sad that there are 5 families without closure and 5 men that are still missing. I am also fascinated and reading
everything I can. I flew gliders in the Hunter Valley and at Lake Keepit for years and canoed the Manning and tributaries many times. I am an expert at nothing but good at a few things and if nothing else, I will continue to follow your progress (in actual fact, I will be part of that October ground support role if it kills me).

Question 1). Do you have the coordinates of the 1st radar sighting ?. (I can't derive enough accuracy from the radar chart to plot it on Google Earth)

Question 2). Was the 2nd radar sighting actually made ?. I note that it was never confirmed in the radio transcript but is noted on the radar chart.

Do we have the coordinates of that 2nd radar sighting if it is confirmed ?.

Question 3). What is the reasoning behind your search areas as depicted in the Google Earth pictures ?.

I am not out to reinvent wheels as I am an 'expert at nothing'. I just want to know for my understanding and further research before I go up there.

Best of luck to you.

Hi Martin,
Thanks for your email. There's not much i can tell you that's not already on the blog site. If you check under the post last radar position you will find the diagram to click on and enlarge to give you the last radar position as well as flight plan booked by MDX. The reason i searched around the pol blue area was due to a sighting that was made by a pilot who said he saw wreckage on a hill side at the top of the headwaters at pol blue creek. Unfortunately this was not the case.

I have now moved my search to the area of Buladehlah after reviewing some of the posts that have been sent to me and not having any new information to go on since I've exhausted my previous search area. It's a needle in a haystack as you know but half the fun is just getting out in the bush and being a part of a search. Good luck with your search as well and good on ya for getting out there and having a go.

Let me know how the search go's in October.

regards

Nev

Hi Nev,
On your VH-MDX blog, Robert Campbell reports (posted 03JUL2009) that the radio transmission is out of order (the actual audio file doesn't follow the order of the typed transcript).
I have edited the audio file and attached it. In doing so it can be seen that the first 4 minutes (page 2) is present as is the last 4 minutes (Page 4 & Page 5). The attached audio file isnow in this order.
For whatever reason the period 0928 'MDX SY Could you squark code 4000....' to 0934 '-DX Say again Maitland' are missing I.e. the bottom half of page 2, all of page 3 and the top bit of page 4. Of small consequence as the most qualified
have computed the search area/s but an observation nonetheless.

Note:

I'm having trouble uploading Martins edited transmission file to the blog. If anyone would like a copy just send me an email and I'll pass it on.
