I suppose I should have been more politically correct and made a response
such as:

Although it is possible to use carpenter glue for aircraft, it is not
recommended. The odds of the wings falling off during flight increase, and
if the wings fall off during flight, the prospect of death increases. It is
also possible to use a glue made from flour and water, but that is not
recommended for the same reason.

If you use a glue such as resorcinol, you will have the confidence that the
wings are less likely to disassemble while in flight.

It is recommended that you follow the plans of the aircraft designer and not
make the spars out of lumber purchased at the local lumber discount store.

Have a nice day.
