Hi it seemed long for a piston prop i/e small light aircraft the wings looked thin and i think the engines were on the wing not like the drones i found on google at the rear. It was pitch black and i was so surprised to see something so low and it was gone in a few seconds so was going reasonable fast. The thing i cannot get out of my mind is how quiet it was two hundred yards and you could not hear it at all.It was also on the same flight path we sometimes see the Red Arrows on.Sorry to be so vauge but it was in sight for less than 10 seconds.Graham

Spotted this flying caravan today, well it is boxy and as slow as a caravan (I was outside and had time to go in and get my camera). It seems to be a Ledcor/Summitair aircraft but they are based in Canada's Northwest so it seems out of place. Does anyone recognise what it is or know where it is based?

Martin,

Its a Short SC7 Skyvan made by Shorts of Belfast, **LINK** they tend to be used these days as a bus for parachutists.

Thanks, your link does mention Summit Air as operators of two of them. Stall speed of 69mph which is why it seemed to be travelling very slowly (flaps down in photo).

Good grief, you need to be poised over the keyboard ready to post these days, or you get gazumped!

The Skyvan morphed into stretched versions, the Shorts 330 and 360. The wing always looked far too small, especially for an aircraft that could operate from relatively short runways.

Sorry Andrew devil I've been out doing my part time delivery job this afternoon and when I got home I made SWMBO and I a cup of tea and I sat down with it and saw an email and answered the thread, I may not know much but aircraft recognition is as you know an interest of mine.

Quite so. I knew it was a Shorts, but I had to search to find it was a Skyvan, which is why you beat me to the reply.

My pilot friend says the Skyvan had a roof hatch in the cockpit, which always leaked..

A sonic boom has made BBC headline news, when I was a boy they were so common you barely looked up to try and see the aircraft. Seems to cause consternation now but I suppose we do have a few more causes of loud bangs. I was mysteriously woken up at the moment the Buncefield depot exploded and I am about 35 miles away.

As an aviation enthusiast I've never heard a sonic boom and even though im only 35 miles from Buncefield I never heard that either but I dont have a problem with RAF sonic booms when allowed as its much better than a rogue aircraft any day.

I didn't hear Buncefield as we were on our way back from gliding in Northumberland. Although it didn't affect us we wondered why there were lots of signs on the A1 announcing that the M1 was closed. My mum in Bedford claimed she heard/felt something at about the right time.

I heard my first sonic boom a few years ago, at the time of the London Olympics. I was in the workshop and there was a loud boom followed by a smaller boom. The garage door visibly shock. We don't have mains gas in the street so I wondered whose oil or propane tank had gone up. Half the street were outside looking to see which house was a smoking ruin. I told my neighbour it sounded like a sonic boom. She was very dismissive, said she'd heard one before and this boom wasn't right. Then the BBC news announced that two Typhoons had been scrambled to intercept a non-communicating aircraft, and had broken the sound barrier on the way down to London. My neighbour had to eat humble pie!

I experienced a few sonic booms whilst I was working in Switzerland (I think that the Swiss airforce might be a little more relaxed about speed excursions than the RAF is). First time, we were working in a Portacabin which shook like the devil. Even the floor shook! I looked around to comment about the apparent explosion, but none of my Swiss colleagues had batted an eyelid. It then dawned that it had been a sonic boom.

I suppose the period when I remember them as commonplace was living in Germany from 1963 to 1966, job to know whether it was the RAF or the Luftwaffe, skywriting was another regular event over the skies of Düsseldorf.

From experience I can state that sonic booms and ejection seats going off sound very similar.

In Bristol we used to get the remnants of Concorde's sonic boom. Concorde, as it approached the mouth of the Bristol Channel, decelerated to subsonic speed but, I believe, the accompanying shock wave would continue travelling ahead of the aircraft weakening all the time. By the time it reached Bristol it was more of a distant rumble than a double bang. The sound of Concorde's engines followed. This was most noticeable on cold, quiet, winter evenings when it flew over at 10 o'clock.

Martin,

As a passenger I wouldn't be to chuffed if I heard a bang and saw a flash from the front of a passenger plane cheeky

Martin C, are you saying you recognise the bang of an ejection seat because you exited an aircraft using one?
