Aero "porn" for a hard working LAME in TSV

[Adam the Akrodude]

Inspired by another topic of mine, I found this for our resident Phantom Phreak! I think this is COOL! Have you built this Phantom Paul?

That's the later F-4S version. I have built the J when I was a kid. I wouldn't mind doing this in 1/72 to go with all the pretty colour F-4's I'm doing. Thanks for posting. BTW I am hard at work today thanks. I spent the best part of 3.5hrs this morning/arvo taking pics of Hornets, Hawks, Caravans, 737's, Fokker 100's etc. It's a hard life but someone has to do it

[Adam the Akrodude]

Impressed! You didn't take long to bite. Glad you're having a ripper day at work. Hope we'll see some of your snaps!

[hrtpaul]

I'll chuck a few up later. I need a way better camera than the clunker I have but it'll do for now. For someone that's not really into F/A-18s, I took quite a few pics. There was some cool tail art and some unusual markings on them

I like how most youtube videos relate the forming of a vapour cone as breaking the sound barrier. It's not called a sonic boom for nothing.

[hrtpaul]

If you listen carefully you can here it mate

[_BlackHawk_]

Not convinced. If he broke the sound barrier that close to the bloke with the camera it wouldn't leave any doubt. I think he probably flirted with it but didn't break it.

[hrtpaul]

I reckon he did. I've heard a Mirage do it in Darwin and it sounded similar to that mate

[Adam the Akrodude]

I'm with Paul on this one. I think he just busts the Mach at the 49 sec mark. There is a audible thump (keep in mind that the microphone would be completely saturated at this point) and the vapour cone (Prandtl-Glauert Singularity "effect") looks well aft - perhaps near the tail at this point. This suggests super-sonic flow over most of the airframe at least.

Two interesting mach busting events I've heard/read about.

In 1986, a Mirage performing a low level display once busted a lot of glass at local rose farms around RAAF Edinburgh requiring substantial payout to these businesses - opps!

A F-105 infamously shattered a lot of glass at the USAF Academy in the late 60's doing a low level graduation flyby. Col. Robin Olds was the USAF Superintendent at the time.
