I don't want to put the same information from earlier posts, but you take a wrong way
Therefore, just check the link below:

There is a post from T.D. Barnes about "MiGs in Area 51". All limits, which Kermit gave you, are included in page. Author wrote:
Being serious, it's only number for memorize which you can't cross. My questions are:
1) How many times you will fly with this speed ?
2) How do you want to reach this speed without diving? Excluding height...
For example, here's a table from "МиГ-15Бис - Техническое описание - Книга I":
Flying on MiG-15 above V = 0.98Ma is associated with pulling to the left side of your wing. Greenhorn couldn't control the plane with this speed without training and practise. But remember, the control above V = 0.85Ma is much harder than under. The best maneuver results you will get with V = 0.6Ma.
Diving in MiG-15 isn't possible without reducing V with airbrakes. It's strongly connected with very heavy reaction on steering above V = 0.85Ma. Following your way of thinking, we can fly V = 1Ma without any imagination... It doesn't work like that...
