Beyond Selidor

I've got two air trips and two train rides. All many years ago.
When I was a final year med student we had to do 3 months in a clinical post for experience - we had no choice where. I got back to Christchurch from holiday to find I had to be in Greymouth on NZ's west coast the next day. They'd booked me a flight which was in a small plane with just me and the pilot, who got me to sit in the co-pilot seat as we flew over the southern alps. I'm a white knuckle flyer so although the scenery was amazing, I spent much of the flight covertly watching what the pilot was doing in case he had a heart attack and I needed to fly the plane (he was in his fifties). So, memorable! (I didn't need to fly the plane).
A few years later I was travelling with my boyfriend from London to Delhi in the cheapest way possible. That was Air Afghan, and memorable points were: a mechanic outside whacking one of the plane's engines with a wrench as we queued to board. An old Afghani guy having a small kerosene stove confiscated from his hand luggage at check in. Presumably he didn't trust them to provide refreshments. Having to stash my boyfriend's guitar in the empty first class area, which turned out to be filled by large crates (guns?) tied down with chains. A stopover in Kabul where we watched MIGs overflying us. A stopover in Moscow where due to political tensions the plane was forced to park at the far side of the airport in the snow the whole time while refuelling, guarded by an armed truck, and no one was allowed off.
A train trip from Delhi to Madras - amazing scenery and fiercely hot breakfast omelettes with chickpea curry.
The sleeper train across the Nullarbor desert, Adelaide to Perth, on which I learned that nullarbor wasn't an Aboriginal word as I'd assumed, but meant null arbor - no trees. I also pointed out some big rabbits to a lady in my compartment at one point, who gave me an odd look and told me they were kangaroos. The distances were deceptive!
