Okay, two things Larry you can clarify if I am not correct.
1) Air starts at 72 will shorten the time to target. On air start retract gear immediately and
do not hit auto climb. Give it a few seconds and the plane should start to level off.
2) Bomber calibration is more complex. So, either come early and practice or
recommended you wing with a lead pilot who is confidently accurate and drop on his cue.
Calibration: Shift left click on the map, the target that you will drop on (to set altitude), move the bombardier view forward and zoom all the way in, use the joystick to keep the crosshairs pinned to one spot while pressing and holding down the Y key. Notice the calibrated speed if not within @ 2 mph adjust your throttle or recalibrate.
Now, be there or be
