Looking back on the logs, it was not even five minutes between the time the "mayday" distress call was initiated and when the VTOL arrived. However, it might as well have been an hour - because the North Koreans fire power did not cease and Psycho's guns were getting low on ammo.
When the VTOL arrived, the amount of lead heading toward Psycho's team reduced, but that only put the focus on the rescue craft itself. They had to hurry if they were going to get aboard that ship before it was blown out of the sky as well. As soon as the doors opened, the team was already boarding the ship. The earth rocked with every mortar blast coming in their direction.
The VTOL departed just before a rocket hit their prior position, only seconds before. "That one was close," Psycho thought, too close.
As they pulled away and began to retreat back to a safe location, the effects of the blast were worse than expected. The VTOL was having trouble getting up to full speed. They had cleared the area, but not as quickly as expected or needed. Just then, another blast hit the back of the VTOL. This made Psycho's heart race the most it had raced the entire mission. He knew that blast was going to put a dent in their plans to make it back to camp. His guess was validated when the VTOL raced back toward the earth.
Psycho braced himself as he knew the crash with the ground was not going to be pleasant.
