Greek press is exaggerating a lot

From various greek newspaper articles I gathered the following:
OA B737 in descent from 20000ft to 16000ft .
Formation of 2 RF4E on opposite course at 15500ft.
B737 at 400+ kts, the RF4E at 800+ kts groundspeed.
If the speed for the Phantoms is correct, that would have been a very high lateral closure rate.
B737 climbed 1000 ft within 2 seconds.
That would mean, they arrested the descent and climbed 1000ft within
2 seconds.
Now if you calculate that, you end up with a climbrate in excess of 30000 fpm.
How realistic is that, and what would be the g-forces implied?
Having been trained on TCAS RA manoeuvers in the sim for the last 5 years,
I never experienced anything as violent as that described by the press.
So let's wait for the investigation, to see what really happened, and how close it really was.
In any case, it is good to hear, that apart from the FA's slight injury nobody else was hurt.
I would like to wish her a quick and complete recovery.
In many parts of the world this would probably not have made it into the media, at least not to the extent these things get media coverage in Greece.
