Around 33,000 attendees are expected to converge on the Orange County Convention Center in Orlando, Fla., for the three-day 61st annual NBAA Annual Meeting and Convention, which starts on Monday. At least three new business airplanes are expected to make their debuts at the show, along with product announcements from many of the more than 1,200 exhibitors that will occupy approximately one million square feet of space inside two adjacent convention center halls. In addition, some 120 aircraft are expected at the convention’s static park at Orlando Executive Airport. The association will also host more than 100 informational sessions before, during and after the convention. While near-record turnouts are expected, the turmoil on Wall Street and Main Street is likely to cast some gray clouds over the event. In fact, some of these clouds came early: Eclipse Aviation confirmed on Monday that it canceled its static display (though it will still have an Eclipse 500 at its booth in the convention center) and late Tuesday Grob–which was declared insolvent in mid-August–canceled its plans to exhibit so it can focus on “serious discussions with our current shortlist of potential investors.”
