A quick visit to Newton's second law indicates a roughly
2 m/s^2 ~ 6.5 ft/s^2
deceleration due to the recoil force (10000 lbf acting on 50000 lb
airplane). From a hypothetical slowish flying speed of 200 mph
(300 ft/s), it would require about **20 seconds** of fire to get
down to the A-10's ~115 mph stall speed.

Whether that's "quick" or "a myth" depends on your point of view (and
on whether I did my estimations correctly).

Did your estimation take into account that the Warthogs engines are still
producing power while they shoot?
