In aviation history reference books and websites, are the Max and Cruise airspeeds listed Indicated or True?

Most seem to use True Airspeed; how impressive would a Mustang's top speed at 24,000 ft be if it were IAS instead of 440+mph?

And how well would the average layman be able to interpret the significance of a given IAS vs altitude?

In reputable sources it is stated. In fast food sources it isn't, thus, you can't know.

Very hard to find any basic aviation information thats in IAS. Its all TAS. Otherwise people would be confused when you give them the top speed of the plane...and its up at 28,000 feet and its "slower" than some other plane that maxes out at 8,000 feet.

The TAS numbers are why everyone starts the game up and goes: "WTF! My plane is undermodelled! It goes 200mph too slow! WTF man! Oleg porked my plane!" Thats no joke because we've seen those posts before. So the numbers are definitely in TAS most of the time.

Yeah, I thought so (TAS) at first, but alot of sources do give airspeed as ### mph @ ##,#### feet . . ., which would seem to indicate Indicated Airspeed. But alot of books and websites(which I consider reputable) do not ever come out and state which one they are using.

They mention the altitude because that's the particular altitude at which the aircraft attains its highest speed.
