Hydroplaning possible...
If you fly jets long enough, you will at least once experience hydroplaning immediately after touchdown (typically right after heavy rain with some threshold amount of standing water that your particular airplane may be sensitive to). In the cast of the Hawker, 3/4 inch seems to be just right. If hydroplaning does occur, braking and directional control may not be possible above 80-90 knots.
The case could then be made for an attempted aborted landing. I have done enough touch-and-gos in jets to know that regardless of [jet] aircraft size, you always need lots of runway (even dry); much more than 5500 feet to do it safely.
