"Over the last decade, the cross-boundary helicopter shuttle
service between Hong Kong and Macau has exhibited continued
growth since its commencement towards the end of 1990. The
number of passenger trips have increased from around 14,000
in 1991 to some 108,000 passenger trips in 2001, with growth
averaging some 23% per annum over the period".
