What is the fastest commerical plane out there now? I mean in service with a regularly scheduled airline, so the Concorde doesn't count. How many commerical jets have broken the sound barrier?

Approximately:
1. Cessna Citation X
2. Boeing 747
3. Boeing 777

Many commercial jets have broken the sound barrier, though in some cases this was not planned..

Thanks, I thought the Citation was right up there, but it's not part of any airline fleet that I'm aware of, is more a corporate jet. How can I find out more information about planes that have broken the sound barrier?

Ask on A.nut and take the answers with a pinch of salt Big grin

IIRC, these have broken it:
- DC-8 in testing.
- Citation X in testing.
- 747 in dive following engine flameout.
- Convair 990?

Citation X is the fastest, but it's not used by an airline, so it doesn't really count for this thread.

Now we're getting into semantics.  Big grin Is NetJets an airline? It's arguable at best.

What is NetJets? Anyway, still looking for information on the sound barrier - does it happen only in a steep dive, or can any of the current commerical airliners actually go that fast?

I don't see the arguable part...it's not an airline. Quite plain to me.

No current commercial airliners can exceed M1.0 in level flight - the only circumstance under which M1 would ever be reached is in a dive. Oh and I suppose if there was a large enough headwind (on the order of 160 mph), your airspeed could theoretically get up to M1 then, as well.  Big grin

As for the very fastest, it's currently the B747-400, which is capable of approximately M0.885. I've explained how this has to do with the "area rule" and the 744's bulging upper deck before, so a quick search should fill you in.

Cheers,

The term Broadband comes from the two primary uses of high speed internet downloading porn (broads) and MP3s (bands)

Depends what you mean by "plane". The space shuttle? The X-15?

If a "plane" has to take off under its own power, then far as anyone knows it's the SR-71.

The SR-71 is the fastest airbreathing plane and, as Timz says, the fastest plane to take off under it's own power.

The X-15 is the fastest rocket powered plane.

And since no one has mentioned it yet, I will: Aurora.  Big grin


NetJets is a fractional ownership company, meaning that you buy a certain share in the use of an executive jet. NetJets provides the plane including crew and maintenance. You provide the cash and can use a plane for a given amount of hours each year.

It's not really an airline in the traditional sense, but aren't charter airlines simply you buying a share in the usage of the plane? It's a fuzzy distinction at best.
