"Supersonic jets shatter Brazilian Supreme Court building"

Do windows really break that easily? :confused:

[stumpey]

Cheep foreign muck, like sugar glass!

Now in MY day bla, bla, bla. :ok:

[innuendo]

Been done before,
From Wiki although there are other sources:

In August 1959, a U.S. Air Force Lockheed F-104 Starfighter performed a low fly-by of the airport during celebration of the opening of a new terminal in Ottawa and accidentally went supersonic over the airport, causing windows and parts of the walls of the new terminal to shatter. The terminal was only reopened in 1960.

Construction of the airport terminal building began in 1957. As the project neared completion, a military demonstration proved disastrous; a U.S. Airforce F104 Starfighter broke the sound barrier and virtually every window in the structure. There was also significant structural damage inflicted on the building. This mishap added approximately one year to the construction schedule, and $300,000 to the budget of $5 million. The terminal was finally opened by Prime Minister John Diefenbaker on June 30th, 1960.

The damage was fairly substantial, quite a few red faces around.

The Daily Wail claims they were supersonic!

At that height..........yeah,right :ugh:

Do you think it is difficult to be super at low level?

[Wander00]

Didn't a certain flt lt (in time to become a 2*) trash a few windows at Barkston Heath with a Lightning in the 60s

[newt]

Well I have to say I did shatter a few windows in a Tac Dive at Gutersloh in 1972!!

Sent to recover a jet from Wildenrath on a Sunday, I got a little over Mach one on my return.

Those were the days:ok:

if only that was all I got wrong!!

[BEagle]

A 4-ship of Lightnings 'said farewell' to STCAAME in fine form one year, progressively getting lower and faster until one of their number dropped a boom and shattered a few windows in Caergolliwog...

F2As, I think, newt old bean?

[TyroPicard]

if only that was all I got wrong!!
And so say all of us.....

[LowObservable]

Spectacular!

& Sitigelfel - Busting the Mach at that altitude in an M2000 is within limits, I should think. Also, clean and light and moderate temperatures help.

On the other hand, someone should have advised the pilots that 500 knots looks impressively fast to people on the ground and leaves you lots of margin before you provide an economic stimulus to the city's glazing business.

[pontifex]

In the mid 60s I was at Headly Court (don't ask!) along with Jimmy Dell who was the P1b (Lightning to you) test pilot. He told a story of the Farnborough show when he was doing a low fast fly past. At that time getting the burners to light together or at all was an unlikely event so he plugged both in. Both lit up and, before he could react appropriately bingo! Broke all the ATC glass and got a bit of a wigging. Those were the days.

[sled dog]

Late 60s, 111 pilot Sqn Ldr ( C - S ? ) making his last flight before a desk job, went past the tower at low level at "only" 0.98, cracked some glass, and after disembarking got his glass of champagne ( and applause ), and so it was said a quiet word from the Staish later. Mighty impressive it was too.

[Courtney Mil]

My twin brother once broke some windows in glass houses in the Haltwhistle Valley by going too fast. Aledgedly. Claimed he was chasing down an F111 on an exercise. He was such a git.

[LowObservable]

CM - Can't have been that way since everyone knows -111s are really slow on the deck. :E

[Courtney Mil]

My brother was a licky buggah. By the time he got back to his secret base in Lincolnshire, the F111 pilot had 'fessed up to being teribly fast at low level (being chased by an F4) and gallantly took the can for the broken windows. My brother was, at least, smart enough to keep his mouth shut.

He said the Aardvark looked pretty fast to him. :ok:

LiveLeak.com - Brazilian Air Force Mirrages Break windows on government building

[OafOrfUxAche]

Looks like a close shave for the Brazilians...

Created a few chilly Brazilians...

Hat, coat, etc...

[sandos]

I'm curious as to what speeds would result in this, how close to transsonic do they need to be?

[Livesinafield]

I don't think there's any broken glass... it seems to be that the mirages broke through the sound barrier causing the noise

[awblain]

At 0:02-0:03s there's lots of stuff raining down from the frontage of the building, which given the clear sonic boom at the camera, and the likely effects of the awning shade over the frontage to diffract and reflect the shock wave makes sense.

The shocks arrive at the ground when the aircraft have moved by to about a 45 degree elevation, so the shocks - and the aircraft - are traveling at close to - within a few percent - of the speed of sound.

They look to be flying straight and level at a steady speed, so there should be no extra shock shedding or focussing effects at work.

[awblain]

I wonder if the missing reflections from the barrel-shaped building in the background are broken windows too, or just open?

It's a shame the video didn't catch the flags to see if they jerked as the shock came by.

[Fox3WheresMyBanana]

The portico/paving around the building may have concentrated the pressure wave.

Maybe third time lucky the glass doesn't break.....!

One of the other videos of this event on Youtube (can't check the link on a work PC!) clearly shows the glass missing from almost every pane (curiously, two or three of the big ones survive) and large amounts of broken glass lying on the ground outside the building.
