It worked on mythbusters!!!!

Sort of:pac::pac:

Emirates big 'bus is fastest of the pack at the moment... 670 kt+

My concorde remark was somewhat tongue in cheek (Mach 2). However could one attain a Mach 1+ groundspeed. If a cruising airliner generally does Mach 0.8 then would such a fast jetstream tailwind not put its groundspeed into the Mach 1+ area? And if so wouldn't that not be a problem for the aircrafts design limits because its airspeed would still be within its flight envelope?

An aircraft is only concerned with its airspeed. It will not be travelling faster than the speed of sound in the parcel of air it occupies.

This is an interesting website for ground speed records

I've lived under the flight path since 10/28 opened - you're basing it on one day on FR24 and one flight...

Well i've been looking the past few nights and weeks and they have done that each time.

To be fair to Owen, he's right. The vast majority of landings at DUB are on 28. That's because the prevailing winds are south westerly, and the preferential runway at Dublin is 28. Even with up to a 5kt tailwind, 28 is preferential. For the few early TA arrivals, if there's no conflicting traffic, ATC might change it over if requested.

There's a difference between the all being claimed by owenc and the "most" which is the case. I'd say that it was a far lower % than normal this year due to the amount of summer mornings where 10 was in use though.

I find that the descent and ascent times prevent a lot of records being beat. Also I noticed when planes come into Dublin they make a turn and go over the Irish sea instead of flying straight in which admittedly adds on about 10 minutes to the journey.

Ah come on. He just said he noticed stuff landing 28 when 10 would be shorter. Give the guy a break.

Followed by an attempt to claim that [from a tiny amount of observation] that they always land on 28.

Nah, he just claimed he'd noticed stuff landing 28, and it added about 10 mins. That's all.

So much drivel in this thread.

Back on topic, no flights will pick up the full strength of jet stream due to the turbulence encountered entering the core of strongest winds. Look at C.A.T. 6 on tomorrow's 6 am chart. Moderate to severe turbulence from FL190-350 to the north of the 160-190-knot jet.

Eastbound tracks tonight planned with the most northerly pretty much at the core, so I'd say there'll be plenty of aircraft taking advantage. The turb forecast is moderate occasionally severe, and as mentioned is on the polar side of the jet.

Unlike some other aviation forums we do allow freewheeling discussion and tangential debates. Using drivel to decribe the input of others posters may be a little strong.

This morning's speed checkpoint: Fastest I've seen - 683 kt. (786 mph)

Comhrá

690 kt (794 mph)

Zonda999

Check out the attachment, Emirates A388 managing a nifty 670 kts (771 mph)! That's the quickest I've ever seen on FR24

FWVT

250 knots later tonight, with 80 knots from FL600 to FL050

I've never seen 250 over the Atlantic before.

There was a 693 knots earlier today.

Yeah only thought there was one page in the thread till I posted, now I see..

Westbound are heading way north of the strongest winds. The first few eastbounds are zipping across now at near 700 kt.

My wife just arrived home, said it was the fastest she ever flew home from Boston in 4h 39m but said it was fair bumpy

looksee

Just had a call from daughter at the airport who said that her flight (due to leave in 5 mins) was either going to have to lose some passangers or refuel somewhere! (going to US)

Into DUB or SNN? If that was into DUB it may well be a record.....
I have managed 4 hr 33 BOS-SNN before.

If my maths are correct, this is faster than the speed of sound! Welcome to the new age of supersonic flight! :pac:

They are trying to offload 50 passengers (looking for volunteers :P)

B757? They have a problem every winter with headwinds across the Atlantic

And they got the 50 they needed.

What would the 50 volunteers have been offered? Must've been worth their while...
