Being a passenger in a hot air balloon requires a certain degree of trust. As you rise, gently, gently, into the air, no seatbelt prevents your toppling out of the basket. No windows or doors or stern flight attendants stand between you and the miniaturised world below. And yet hot air ballooning is perhaps the most calming of thrills &mdash during the course of one hour afloat over Rajasthan you experience nothing short of suspension in time.
