I think this is the first mention we have seen that there is a regular service into St Helena, that Basil Read, the airport contractors, have a monthly chartered Bombardier Challenger coming in. Someone commented above that it was surprising to see it in a corner of the RAF Hercules photo.
If I am not mistaken, we have had a range of aircraft now come in, and the only one that needed a missed approach (one) was the Comair 737. Presumably the Challenger operator has no difficulties with it.
