But both the BAe146 and the B757 are becoming museum pieces, surely St. Helena should be looking to the future rather than the past.
I have to admit that I don't fully understand windshear but would something like the A318 be of any use? ... If it can operate JFK/LCY, albeit with a less than maximum payload, then it must have a reasonable range/endurance and if it is approved for 5.5 degree LCY approaches then would a 5.5 degree approach in to St. Helena assist with the problem of windshear at all?
