Uhhhhh..... why?? How the hell is a Typhoon supposed to help a helicopter anyway? As for the distress signal - has the media stuffed up the fact he was maybe squawking 7500?

Best regards,
Vulcan.

I heard the story second hand from a friend but they said the helicopter was accidentally broadcasting on an emergency channel. The Typhoon wasn't going there to help the helicopter but to be ready to shoot it down if it turned out to be a hijack.

Finger trouble on the transponder looks like - probably a single-digit entry one, he's been told to squawk VFR and he's had one of the digits set already.

Almost happened to me a few times, but I always switch to SBY, change the code, and then verify it before putting it back onto ALT - just in case!

The media don't have people that know these things any more. Aviation correspondents no longer exist, and evenn the specialist defence correspodents, even in the broadsheets, are liable to gross errors and lousy journalism.

As for why, 7500 finger trouble it almost certainly was, and a damn good reason to go supersonic too. Probably explained why they remained airborne late into the evening too, just in case...

Had it been the early 50s, I doubt anyone would have made a fuss when airshow sonic booms were commonplace, and the aviation industry was major news!

This made me giggle though, amongst the rest of the quote in the news:

Quote "Mandy Leech, 44, from Coventry, added: “If it was just somebody accidentally pressing a button in his helicopter I won’t be very happy because it woke my baby up and scared the life out of me.”


Get over yourself woman.

I remember many years ago when I was in the Merchant Navy being startled by an Air France Concorde going across the Atlantic. I was on a BP tanker called the Sivand at the time and we were heading north towards Europe, As the boom hit us a large chunk of rusty metal fell off the top of the funnel and landed in the crews swimming pool ! It was only when we looked up and saw the contrail shooting across the sky that we realised what it was. A few radio calls to the appropriate bodies got the reply back a while that it had indeed been an AF Concorde on its way to Rio de Janeiro. The noise was an incredibly loud BA-BOOMMMMMMMMM !!! and it rattled a 250,000 ton ship !

The light at the end of the tunnel is a freight train coming the other way !

@dodgy-alan: I bet you won't forget that!! People used to go out on boats to the LANDD intersection - Concorde would be supersonic at that point (around Mach 1.4) to hear the sonic boom.

Take a look at this. F18 breaking the sound barrier at low level for the Mythbusters show, and blowing in a window.
 
Can a sonic boom break glass? 
 
They worked down to 200 feet.
 
Adam blacks out in training at 7.3 G and throws up. He did well though. Awesome takeoff.
 
 2:12 in for the Blue Angels experiment.
