Yes, the chase plane had to stay within 50m of the 727 which was a bit of a problem because the top speed of the chase plane was close to the stall speed of the 727.Amazingly you can buy a working 727 for $300k, I thought it would be a lot more.
The program is a bit of a tease because you have to watch a while to see the crash, but it was interesting.
As I recall I was rather disappointed in the 'crash' as it seemed to be more like a high speed landing gone bad rather then a near vertical crash I was hoping for.
