per post 8 and the stats:
- 2013 to 2016 there was a steady decline in hours flown - 35,000 hours over that 4 year period
- the average of hours per year between 2013 to 2016 was 222,000 hours per year
- Against this trend - all of a sudden in 2017 we have 379,000 - a 70% increase on the 222,000 average above ..........a huge jump in hours flown
- why such a big increase in the 2017 hours ?
