an anyone assist me as to whether it is (a) legal and (b) safe for Thomsonfly passengers to be held on a 757's steps for 25 minutes while the aircraft was refueling in Palma.?
It is both legal and safe, but also undesirable and unusual. Was any explanation offered? For example, could an anticipated imminent completion of fuelling have been delayed by a bowser fault, or the bowser simply running out of fuel? These are just guesses, since the situation you describe in not a normal situation
