Those planes can take passengers too
Sandeep Unnithan reports that the Sri Lankan troops who captured airfields and landing strips used by the LTTE didn’t find the two Zlin Z-143 planes that made up its air wing. Some analysts think that the light aircraft could have been dismantled and stowed away in the jungle. (via R Hariharan’s MI blog)
There is also another possibility. The four-seater planes with a normal range of over 1000km (according to the manufacturer’s specifications) could be used as getaway vehicles for LTTE’s top leadership. Given that these aircraft have successfully evaded radars and air-defence in the past, there is a good chance that the escape has gone (or will go) undetected. Indeed, an organisation as astute as the LTTE might well have set-up a contingency plan, with a camouflaged landing strip on a remote beach far away but within range of the planes; next to a jetty with a high-speed boat with an even longer range.
So Velupillai Prabhakaran & Co could be very much anywhere by now.
