Bearing in mind the accident didn't occur until sometime after 1800 on the 2nd of June, I imagine 'freeing up' a comms aircraft less than 8 hours later does not necessarily indicate any shortage of aircraft.
After all, how long would it have taken to identify, select, contact, assemble and transport the BOI to a suitable pick up point? Never mind assemble and brief a crew.
On the other hand if that part of your post was superfluous, and irrelevant information, then fair enough.
Only a thought.
