## Ah, er, so how long will that be?

(OP)

#### Quote (CBS News)

For 3 ½ hours, the eclipse follows an 8,500-mile path. Viewing, from beginning to end, lasts about two hours.

The Whole Story

### RE: Ah, er, so how long will that be?

This is the article I've been referencing since I live in SoCal and it spells-out the times in an unambiguous manner (which for the records indicates that at least for us here in the LA area, the eclipse will last a bit over 2 hours:

To an Engineer, the glass is twice as big as it needs to be.

### RE: Ah, er, so how long will that be?

So is that in normal hours or light-hours?

### RE: Ah, er, so how long will that be?

Two earth hours, 3.5 space hours

### RE: Ah, er, so how long will that be?

If you can follow the arc at a speed of 2429 mph, you can view it at its maximum extent for 3.5 hours. If you view it from a stationary position you get two hours from min to max to minimum extent.

### RE: Ah, er, so how long will that be?

So if you have a plane faster than an SR-71 Blackbird you can see the whole show.

### RE: Ah, er, so how long will that be?

I suspect the windows in the SR-71 are less than optimum for eclipse viewing.

### RE: Ah, er, so how long will that be?

And this topic is language/grammar etc. how?
