There is no guarantee that the one on the plane did not have a leak (presumption). Otherwise, use high quality condoms as the Surgeon General's Office warranties that they are free of leaks. The other problem with these tests is a change in the barometric pressure. Higher baro, smaller balloon and vice versa. Maybe a better test would be to use a water tube loop mounted vertically and calibrated in inches. Take a barometric reading when sealed and also the next day and correct the resultant water level reading. This way use can test with both positive and negative pressure.
