Well that's not too bad..Probably be a good idea to have a wall or catch fence between the two at some point.
Absolutely NOT. There must NOT be a wall or any other physical barrier separating the landing strip from the racetrack straightaway.
A wall in this location would be there in a high speed impact zone to hit 100% of the time and it doesn't move away in response to a command from an air traffic controller, and it can't arrange for its "disappearance" depending on track conditions. An airplane can, except maybe if it's making an emergency landing, but then highway 81 (just on the other side of a field from the airstrip) is in just as much danger.
Dunno if folks noticed, but it was apparent that the aircraft that made a landing during the endurance race made some zigs and zags so as to time its touchdown on the landing strip during a gap in the traffic on the track. A pilot with eyes and a brain (and a radio connected to air traffic control) can do that. A wall can't.
It's fine the way it is. If Grand Bend Motorplex decides to morph itself into Grand Bend International Airport then maybe it's an issue. But for two or three light planes a day, it's a non-issue. Note that a vote was taken in Sunday's rider's meeting if we were okay with aircraft landing and taking off without interrupting the racing. The vote was that we are okay with it, and presumably that also means the pilots are okay with it.
Question for those that know; do the marshals and race control have communication with air traffic control on this? If an aircraft calls for an emergency landing then it's probably best for race control to call for a red flag.
