Hi,
Loading BDU-33 and CCIP-ing them (not jettisoning the pylon) seems to affect the drag model of the Hornet allowing it to accelerate close to mach 1..46 on the deck and over mach 2 at FL350.
Here's is a video showing the bug with a sea-level test:

Test was conducted on Caucuses on the Multiplayer server "Through the Inferno".
As you can see in the video when the BDU-33 pylons are jettisoned the speed is reduced dramatically.
