If you pass your pilot’s licence, don’t think of trying to impress
any existing or prospective business partner by flying them to France
for the day for ’a spot of lunch’.
It’s bound to end in tears, for a variety of reasons. You might a) take
longer to cross the Channel than planned and miss lunch-time opening
hours in your specially selected brasserie; b) find the airfield is shut
when you finally return to it, thereby forcing an overnight stay; c)
thick fog could mean that your plane, once airborne the next day, is
diverted 40 miles away from where you planned to land, causing yet
further aggro to said client (who has already missed a meeting, had to
spend the night with a strange adman and been in the same smelly clothes
for more than 24 hours).
We know this could happen to you because it happened to the hapless
Frank Bailey at Hodder Wilson Pearce and Bailey.
